Okay, you should rent this movie immediately, even better, own it, hear me out;
Here is a small overview (light spoilers but not many):
A woman is trying to escape her crazy, abusive, insane husband/boyfriend. He becomes invisible and starts messing with her, stalking her, scaring her, etc. She goes to a friends house and stays there for a majority of the film before eventually she goes somewhere else (wont say bcus spoiler.) Now, the way he becomes invisible impressively isn't corny. Its not some potion, or a spell, he uses science. Still sounds corny, but when you see the way he does it in the film, you'll be left with the same thoughts as me; "wow they really thought this out." The director even said in an interview "well I didn't want it to be corny" (not his exact words but a good tldr of what he said) anyways is the movie good? Yes. Should I/You watch it? Yes. Watch it. Watch it now. Be a good, human, (or helicopter idk what ppl classify as) and watch it.
