I missed this in the theaters, even though my girlfriend and I are huge Simon Pegg fans. Unfortunately the way it was marketed when released made me think it was a romantic comedy / follow-up to the Devil Wears Prada. I also had no idea that Simon Pegg was the film's lead (which would have been a driving factor to get me into the theater). With that said, I really enjoyed the overall feel of the film and found it far more entertaining than Run Fatboy Run, a film which didn't allow Pegg to do what he does best ... which is be damn funny.
While not in the same genre of films that Hot Fuzz and Shaun of the Dead blazed into, this film is a nice balance between a mild romantic comedy and some stinging satire regarding the ridiculous relationship between print media and Hollywood's elite. It's definitely worth watching for Pegg's performance, and Kirsten Dunst is far more likeable here than in the latest Spider-man film, playing a more complex and human character than MJ part trois.
In regards to the low rating the film is currently seeing on Amazon, I can only say that it's disappointing the film didn't do well in theaters, but regardless of the lack of extras and tomfoolery going on with MGM's home entertainment management, it's a shame that people are rating the film so poorly. Unfortunately, if people just see the listing for this film with a paltry two stars and don't go on to read the reviews they'll miss out on a refreshing and entertaining comedy starring one of England's funniest, freshest and most talented actors.
On a side note, I'm continually impressed with the range of actor Jeff Bridges' in his portrayal of various characters in his many film roles. His turn as the villain in Iron Man was memorable and I found his portrayal of media mogul Clayton Harding to be entertaining and an excellent compliment to Pegg's hilarious Sidney Young. Definitely worth your time to rent and perhaps even own if MGM gets smart about releasing a revision of the DVD with proper extras (or how bout a Blu-ray edition MGM ... I'm sure we'd all eat that right up!)
