Takes a while to get going, but when it does, it's very good TV. Eric McCormack's acting is excellent, and it's really nice to see a main character dealing with a mental illness whilst still having an important role to play within his fictional world, and within the show. And his character, Dr Daniel Pierce, does not merely have safe little hallucinations then go back to normal, he does really struggle with his illness. The fact that the show manages to explore these issues sensitively whilst staying watchable and entertaining, is a testament to the quality of the writing I think. The premise of a FBI consultant with 'special powers' (in this case, his hallucinations) may have been done before, but this mental illness approach does put a new twist on it, and does it very well. Every episode is good. If you like American procedural dramas, or Eric McCormack, you wont be disappointed with 'Perception'.
