I like Simon Pegg. I think he's a naturally funny comedic actor. But, like most actors, he sometimes ends up in a movie that just doesn't work. That's the case here.
Here's the scoop. Pegg is the publisher of a bargain basement entertainment industry rag. Because of a stunt he pulled, that ended in a real disaster, he gets hired on by a top shelf American entertainment rag run by Jeff Bridges. He's a fish out of water in the new job and one blunder leads to another as he tries to pursue his dream.
Given the set-up, this should have been a slam dunk. It's been done many times before, so the story should take care of itself. It's cookie cutter stuff. The focus should then shift to how they use the talents to pull off the gags. The opening 25 minutes or so are a riot. Pegg is as good as he's ever been, but then things go south. This does get messy. The writer/director doesn't seem to know how to play things. For instance, in the third act, you find out something about Pegg that is way counter intuitive to how he behaves. That's just bad character development. Then there are other items that seem to be crucial set-ups for events to come later. Nope. They just let them die. And the ending?! You've got to be kidding me. Lazy. How about Pegg's rise in the ranks. At one point he was on the short end of a pink slip. Now he's at the top for no apparent reason. Go figure.
Kirsten Dunst, Danny Huston do genuinely decent jobs, Bridges, as much as I like him, wasn't invested in this role. The writing certainly didn't help him. Everything else is on par with the project. This fails at the script level.
This isn't a painful watch but your time might be better spent somewhere else.
