TREMORS 3 is kinda weird as far as sequels go. Not only was the story better than the one from the second movie, but it had even more returning cast members from the original film than the second one did. Six as my counting goes (Yes, I'm counting the actor who played government agent who was a road crew worker in the first film). That said, while it is a fun film, it's nothing mind blowing and you can tell the budget was very low.
Good acting, nice pace, fun characters, well thought out story, world's fastest microwave, dated special effects, interesting Graboid life cycle facts, satisfying ending that was continued in the short-lived TV show. Definitely worth a watch for Tremors fans.
