Part 2 & 3 are very weak in comparison!
The Return of the Living Dead (1985) feels genuine and still holds up for the most part even in 2020. It’s a fun flick. Original and cool, dark and gritty.
In comparison part 2 is a lame horror comedy without horror and comedy.
Part 3, directed by the hack Brian Yuzna, was a love story based on young love, teenage angst & set in military facility. Nonsense.
