Watched the entire series recently on Prime & this one on HBO, and just like the rest of the other films there's a slow start introducing characters and plot to get the ball rolling, then the fun starts when the body count begins. What's weird is the 1960's flashback at the start of the film. I doubt there is any relevance to that date, but merely to introduce newcomers to the series about Victor Crowley (follows the formula for the first 3 films where someone dies at the beginning). Directly after that scene they narrate his origin story to set the tone, but I thought those scenes were unnecessary. Hell, I think the movie can do without those scenes, but it definitely serves as a setup for the coming death scenes.
The practical effects hold up great; they work well in the death scenes and for a villain affected by voodoo. Other Horror franchises that try to be serious and intense are irritable, and mostly unbearable. And because there are purely practical effects, tells that the story doesn't need to take itself seriously. body parts don't rip off through sheer force! even the sound effects contribute to this idea. limps flying that sound like raw meat slapping together; I honestly laugh every time.
That said there is some predictability as expected, but watch it with the expectation you had with the first film (campy, hilarious, brutal, fun) and you will enjoy it. The kills are worth the watch; you get a myriad of death scenes ranging from brutal to sad, but the funniest death had to be the writer's agent - it's sick and twisted, and it gave me a good laugh. Some nudity, but surprisingly not during any deaths. Enjoy the ride it for what it's worth.
