I personnally liked the sequels a lot better as B-movies.
Everyone talks about the shock ending of this one but I feel that's the only thing interesting at all about it myself as the movie is just too dated for me & even that shock ending was pretty boring to me but I guess that's probably because I saw the sequels 1st. This movie is def. disappointing out of sequence IMO. So if anyone hasn't seen them, watch them in order. If you're already out of order, maybe not bother with this one?
I guess it's akin to watching the Star Wars sequels in "proper" order. That "Luke I am your father," line can't be as impactful that way.
