Saw it. It was OK

Pros:
- Despite the Foo Fighters not being good actors, Dave Grohl actually did a decent job.
- Pretty good kills and way gorier than expected
- Throwback to these type of horror comedies/band movies from the 70's and 80's
- More of the jokes hit than missed. Very self aware of what kind of movie it is.

Cons:
-Way too long at almost 2 hours. Really could feel it starting to drag towards the end
- As mentioned before, the Foo Fighters are not good actors and it's really hard not to notice sometimes
- Third act was a bit weak
- Almost no music from the Foo Fighters

Overall, I'd say it's worth a watch if you're a Foo Fan, but not something you need to go see in the theater.
