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.
I’ve played very few movie-to-game adaptations, but one that I did play was Total Recall for NES. It’s fairly ass, imo.
The game does follow the movie fairly well, although I can’t say I recall Arnie pummeling dozens of hobos in a cement factory in the movie x)
The controls were fairly stiff and difficulty quite high up there, it was on NES after all.
Total Recall was quite bad, as were most NES movie based games. Dark Man and Nightmare on Elm Street were also really bad. I loved the Nightmare on Elm Street movies as a kid, so I really wanted it to not suck.
Total recall was my first thought as well. But I’m sure there’s got to be worse ones than that.
Probably the LJN’s entire NES-catalogue? IIRC they were pretty much all some media-property-license-schlock.
