Case for the defence
Watford's first of their four goals perhaps owed as much to Troy Deeney's expert curved run which saw him elude the bewildered Murray Wallace and bury a finish beyond Alex Smithies, while both of Almen Abdi's goals came amid rather mitigating circumstances.
Indeed, the primary gripe for both interim manager Mark Lillis and his players in the post-match debrief was the manner in which Town conceded their third goal.
They were given two warnings and they failed to heed either, with Wallace hauling down Abdi and Daniel Tozser's free-kick being tipped away by Smithies; the fact a former Terriers target in Keith Andrews nodded home the ensuing corner may do little to lift the mood.
Having shown a steely resolve to get themselves back in contention, the sending off of Gabriel Tamas should have acted as the catalyst for a strong finish from Town.
Instead, it led to momentary loss of concentration from Lillis' charges and it was exploited in the extreme by the Hornets as scope for three points soon swung the other way and vanished completely when Abdi coolly slotted home on the counter.
It was the fourth time Town have conceded three or more goals in all competition so far this season, something which needs eradicating sooner rather than later.
Work still to be done in the transfer window
In the build-up to the Vicarage Road visit, Lillis had alluded to a potential need for both central defensive and attacking reinforcements.
This game may have been enough proof to press any potential plans into action after watching a defensive display which, while caveated by the brilliance of Deeney and his partner in crime Forestieri, was ultimately lacking.
Midfield, centrally at least, was a plus point on this performance but there could be cause for concern on the flanks if Sean Scannell and Danny Ward are allowed to seal moves away from the club in the dying embers of the transfer window.
James Vaughan was rewarded for a strong showing, overlooking his unfortunate own-goal, in midweek against Nottingham Forest which illustrated he has stepped up his fitness considerably.
But the pressure on him and Nahki Wells to deliver will be exacerbated by a failure to bring in an additional frontman and relying on a player who for all his talent has injury ills which are difficult to overcome.
Town could have benefited from extra presence up top
Hindsight - as they say - is a beautiful thing. And indeed there is an argument to be had that Town's problem in this game was a defensive one as opposed to an offensive issue.
A quick glance at the scoreline indicates as much.
But there was a lingering suspicion as Vaughan fought valiantly but in vain to stretch the Watford defence that the sole spearhead would have been best suited with someone to play off up front.
He made some intelligent runs and gave up few if any lost causes, but he was beaten aerially and the task of hassling and harrying three central defenders was made perhaps an unnecessarily taxing one by the decision to go with just Vaughan.
Likewise, his presence preoccupied defenders for Bunn's leveller early in the second period as the ball pinged around the area following Scannell's driven cross into the corridor of uncertainty and there were chances that went begging, epitomising the part Town played in the six-goal thriller.
But it was difficult to escape the idea that Vaughan, who it should be noted is yet to reach peak fitness, was yearning for support alongside him.
Positives should be taken
On the face of it, this represented zero points, a third defeat from five and four goals conceded.
Dig a little deeper and fans may be pleasantly surprised with what they find, after all this was only the second time in the league this season the Hornets have conceded more than one goal.
Furthermore, Town got off 27 shots on goal and of those, 10 found the target, representing their highest totals across both fields in league fixtures this term and demonstrating both the high-flying Hornets' ruthfulness in front of goal, charitable refereeing to allow a barge on Bunn in the build-up to the second and equally generous defending on Town's part for Andrews' goal.
It can be hoped that the errors can be removed on the training ground, likewise the experience Wallace in particular will have received from an afternoon attempting to thwart a top marksman at this level in Deeney will prove invaluable in the long term.
One possible frustration? That there is no chance to recover quickly from defeat, with the international break ill-timed in that it disrupts the work Lillis has put in place, which has helped yield visible signs of improvement in performance and morale since the exit of Mark Robins.
Deeney proves the difference
If it hadn't already been made patently apparent, there are no prizes for guessing who the man of the match was at Vicarage Road.
Given that he was one of the top three goalscorers in this league last year and that the two who finished above him - Ross McCormack and Jordan Rhodes - have moved for £11m and been the subject of a failed £12m bid from a Premier League club respectively, his pedigree at this level is undisputed.
It rams home the calibre of player Town will come up against this season but it is something they will surely relish and most certainly learn from after being on the receiving end of a masterful forward display.
Vicarage Road seemed illuminated by news of their talisman's new contract and he, too, revelled in the decision to stay and fire his side into the Premier League - making inroads into that exact objective by netting the opener with a great run, first touch and composed finish.
His and Fernando Forestieri's devastating form up front has seen Matej Vydra forced to settle for a place on the bench and on this evidence, it is clear that Deeney remains the star man in attack.
