War of the God Monsters (1985) AKA The Flying Monster
If "Things" was a giant monster movie, it'd be this one. I'm still unclear just how many movies are being shown in this film. At times, it's about a kid and her father. Other times there are giant monsters attacking something. And still other times, random scientists doing random things! It's like a ten-year-old made a monster movie though that might make more sense.
I mean at about the 57 min mark. a giant monster attacks a pier and the leading lady gives it a look that would normally cause the porn music to start. And she does it a few more times with different monsters (the hussy!).
