'Fanboy Grading' - where a company release gets praised due the makers name and not on the quality and accuracy of the kit itself. Airfix, Eduard, Tamiya and others have their diehard fans meanwhile other companies are often maligned however nice their newer moulds are. That's not opinion, just spent time on the various forums and FB groups and the same uninformed comments get repeated at regular intervals.
I find this year's new kits no different to most others, generally uninspiring as I tend towards unusual, physically small subjects so 1/48 and large 1/72 kits rarely excite. However I do like the idea of the forthcoming MiG-17, and maybe the Tiger Moth, and just hope they don't have any of the avoidable issues that seem to befall some kits (of many manufacturers).
Re: Vintage Concorde - You'll note I gave valid reasons as to why I find disappointing, as I would with any kit judged on merit. Your assumption that this somehow represents a negative attitude to Airfix in general is simply wrong.
It is the 53 year old mould of the prototype (or rather unfinished design) and very unrepresentative of the familiar production aircraft which may, or may not also be rereleased with the confusion of the V numbers. Also that Anniversary should have been a big marketing bonus , and as such is a missed opportunity.
