Lifeforce
There are some trying to rehabilitate this as a modern cult classic. That's perhaps a step too far. The director did very much admit to wanting to shoot a Hammer Horror on a Hollywood budget and got his wish. The effects aren't half bad for it, but they forgot to pay the screenwriters or something because the script is truly bad. Originally titled "Space Vampires" and might have done a bit better with more realistic expectations under that title. Not so bad it's good, there are some redeeming features, but overall just bad.
Drawbacks in 2025 terms are that it took most of the film to find clothes for the lead actress and an extremely cringe interrogation scene where the actor psychically "knows" the poor woman is a masochist and needs the information abused out of her.
