the sunday times reviewer said of this: "the best british comedy in ten years" or words similar to that effect. which is weird. because you think the sunday times reviewer would have seen hot fuzz or shaun of the dead... which also starred the (now very insulted) simon pegg.
this film is instead one of the most average films i've ever seen. a barren plot holds it together, but neglects to allow any characterisation, comedy or memorable moments (other that that clip of pegg killing a chihuahua that was used every time this film was advertised). you would expect so much more from such a cast of high quality actors (and megan fox)... but you'll be sadly indifferent.
