I must admit, I came into this movie with very low expectations. Jack Black to me cannot carry a movie in my humble opinion, but I do like his music.
I was surprised at how entertained I was. I'm not saying this is Blazing Saddles, but it did have its moments.
Kyle Gas was very funny. He's Jack Black's sidekick in Tenacious D. He's also a pretty good guitarist. He played a pretty good straight man to Jack Black, and he got a thumbs up from me.
Jack Black was predictable. He overacted. He was annoying. He was a scene stealer ...everything that makes me not like his movies. But oddly enough, it sort of fit the script.
As a special treat, Dave Grohl plays the devil. That alone made the whole movie worth it.
The songs are funny, very over the top, and theres is also a special appearance by Ronnie James Dio.
As a special note, the kids who played the younger version of the two were dead on. Kudos to casting.
I give it 6 stars, with one extra for Dave Grohl
