I agree with the rating, but I gotta say that I actually really liked P. Diddy in this. He seemed to fully commit to the ridiculousness of the story and his intensity to the craziness of everything made his scenes the best of the movie for me. Russell Brand is at his peak in this film. Just fun to watch and he lent a surprising amount of subtlety to the problems with being an artist (full disclosure, I make music on the side and found his artistic impulses to be an exaggerated version of artistic anxieties even though his are on a mega star scale). The way that the movie mocks the excess of celebrity culture is really the highpoint. I also appreciated the ties it had to Forgetting Sarah Marshall as being familiar with it laid out some good ground work in character development that I was glad I didn't have to sit through in this film. My problem with the film comes in the predictability of the plot, particularly with Jonah Hill and his character development. You could have easily laid out his whole arc from 10 minutes into the film. I'm a little bummed in hindsight that Elizabeth Moss was so underutilized here as well, especially considering that she has been so great in The Handmaiden's Tale. Fun film that coasts by on the lead actors charisma and a good weekend movie.
