I'm certainly a bit cynical when it comes to marketing, I'll give you that. To be honest I don't "get" the admiration for Best Impressions either- they were responsible for the VTEC livery which in my opinion looked terrible with those silly red ribbon stripes. They were also behind Yorkshire Tiger which was an utterly hideous look and brand that meant nothing to the communities served.
I'd agree the VTEC livery was hideous, and that being the case I'm amazed TfW are keeping it on the Mk4s. However, even the best companies sometimes make mistakes - nobody is perfect. However, the whole London Midland package was an absolute masterpiece, as are many of the bus packages (though I'll admit some are a bit samey in terms of stuff like font).
The company isn't perfect, but they certainly seem to be one of the best out there, and unlike some marketeers they deliver a whole "look and feel" package rather than just a fancy livery.
(Avanti of course have a bad look and feel package
and a bad livery, though to be fair this also reflects a badly operated TOC so is maybe accurate! It's all as drab as blue and grey, indeed the greeny blue/bluey green isn't far off old BR blue. I'm well aware the colour scheme is meant to reflect the Italian flag, i.e. white, green and red, but it is just so awfully drab, not quite the right colours for the flag (unlike FS's own liveries) and obvious that it's vinylled on top of "factory" white on the cheap).
What is sort-of of note is that the old VT livery with the silver and red isn't that far off the Frecciargento livery - maybe they should have gone with that! In Italy they would be Frecciargento as medium speed non-LHCS IC services, I guess HS2 would be Frecciarossa. Though to be fair the FS liveries are a bit basic!
I'd disagree with you on Yorkshire Tiger, though. I think it looks, er, grrrrreat! (sorry, I'll get my coat!
) Far better than the drab light blue of its then parent company Arriva.
