It's a movie worth a watch, especially if you liked the first one. Casting is terrific and all the actors do a good job, there's some surprising comedy that's done pretty well. Bill Hader and James Ransone are very good. The production is again - strong, it's a nice looking film just like the first one, there's plenty of violence and there's some really nicely staged scenes, nicely shot, well acted and gets you invested. The theme of friendship is present throughout and is probably the most consistent part, because there's plenty of rifts here - especially since the movie is 169 minutes, there's going to be ups and downs and there is, unfortunately. The movie also does some real ludicrous shit, which I suppose is fitting since the source material is even crazier. Could be a hard sell for a casual viewer, though.
The downfalls are probably its runtime and lack of real emotion, there's plenty of drama and it's competent but it just lacks a bit of a punch. The runtime leads to segments of great viewing and segments of not so much. The scares are pretty lacking, can't say there was any real earned scares or creepiness. I was never tense or scared, maybe once, but that's it. It's more of a casual thriller but with some unusually brutal kills and scenes. That's about it. Shouldn't be a hard watch for anyone who isn't a fan of horror. These are just my initial thoughts, saw it 40 minutes ago. If you're asking for a rating, I'd probably give it a 5 or 6 out of 10. I gave the first one a 7/10.
