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.
There were a lot of absolutely awful ones when I was kid, so many I just forget them all. Back then we had a ZX Spectrum and the games cost like £2.99 each so you can imagine how much effort was put into them. I understand why the studios keep cranking out crappy movie tie-ins and why they keep selling well, because when I was a kid if there was a movie I loved I’d jump at the chance to buy the video game for it. Back then there was no internet to instantly check reviews so you just bought whatever had good box art.
I remember the Jaws game being particularly depressing. It was one of those classic games where it just drops you in an environment with no instructions on how to complete the game or anything. It was just a maze with loads of moving things that instantly killed you. I generally just moved around until I ran out of lives then tried again.
