Do marketing websites reflect anything about the products?

I like to check out websites for upcoming games, and games I'm playing. Mostly I go looking for wallpapers to rotate across my desktop (I have dozens of dozens). What I don't understand is when such a good looking game has such a crappy website. If they can't hire a company to build a website to their standards, perhaps they have no standards and their game sucks...

Witness the crap that is:

Dive In

[ Psychonauts ]

Enter

[ Resident Evil 4]

Should I let the sites influence my opinion of the games? Sure I know that the website was probably built by some other company, and I know all the reasons that crappy websites get made, but I still can't stop these sites from making me think twice.
