You're missing the point.
Sure, you can find something good about the worst game ever made.
But games can, and should, and are, compared to other games like them. Compared to every other shooter on the market, or even released in the same year, AvP2010 was sadly lacking. You couldn't even duck or aim down your sights, for pete's sake. It's this lack of things that hurts the entire game. Some parts were great, I admit, especially the opening Alien level, but it just didn't have enough to compete.
Even compared to older AvP games, which should've been an easy challenge, AvP2010 fails in every department besides graphics.
How do you get a newer game with better technology doing worse than the older games that were extremely limited by comparison?
You have a crappy product, like AvP.
A lot of people still like it, and I play it once in awhile, but this by no means makes the product any less crappy than it objectively is, by a comparison basis.
I'm not saying you shouldn't enjoy it if it's your thing, but there is a standard.
