Good watch, would watch again, and can recommend.
The Tremors franchise is not a great one, but they've managed to make it a lot of fun over the years, and I really thought we were done with it.
I'm not sure why they added Jon Heder, but I wasn't sure why they added Jamie Kennedy either, but pulling "The Grabboid Man" into a situation unprepared because rich people didn't care about the consequences of playing god with extinct animals (yes, like "Jurassic Park"). It's even on an island.
They added a new look and behaviors to the creatures, but it is a movie fueled by stupidity and pride. And you can tell the scientists are the good guys because they're not making (as many) stupid mistakes. Even that ladies they take up the "obligatory hot girl" slots elevate the characters properly in the bad-ass and intellectual roles.
Ultimately if you like Tremors, you should like this. I did get a bit of a "Crystal Skull" vibe with Heder coming in to get Michael Gross, but it faded after a bit.
