For me, it has to be Alien: Colonial Marines as it’s terrible due to inconsistent frame rate (moments the game ran smooth and times where lag was insane, even with the best hardware). Both player & enemy AI is crap since the combat wasn’t even that immersive plus Xenomorph AI isn’t as intimidating due to it being poorly implemented.
The movie is Besson-core, full of busted plot points and stupid ideas, kitsch as hell but at least made at a time when he still gave some fuck. So it was still entertaining, and I liked it back then. I mean, I got the game (on PC in my case) because of it.
I get why it is still somewhat pop-culture relevant. Unlike most of Luc Besson’s career as a producer and director since then. Most of it is seriously unwatchable. Aaand even though there were signs before, now we know he’s a creepy bastard, which doesn’t help enjoying his movies (but certainly explains how he treats some of his characters).
