You may wonder why there would be another one of those? But then again, fans of other franchises could only dream of their favorite character coming back on screen. And Grummer seems to be just that. Impossible to kill off (no pun intended) and in all movies Tremors related (probably even in the TV spinoffs and whatnot).
This time his sidekick is someone most people will know from the Scream franchise. And/or from conventions - and if it is the latter, the character he portrays seems very close to his actual personality. Then again, maybe a fusion has taken place where you can't decipher if he's fooling around or actually that ... guy 24/7. Having said all that, some may find that intriguing and funny and others may find it very annoying. Up to you to decide, you should not be easily offended by the way.
Visually this is top notch and the effects are quite alright for mostly CGI (especially the first movie is known for its hands on effects which were awesome) ... funny or boring, depending on your threshold, but with a franchise to back it up and give it some life - just don't question the "wisdom" and the evolution ... and the coincidences and ... well you get the point(s)
