Monk really is OTT with OCD as he travels to Mexico to sole a murder under very mysterious circumstances. By the end, his hoarse voice (because he refuses to drink Mexican water, even if bottled) is not only about to crack, but grates big time. I really like Monk, but this episode won't really go down in the analls of the fine Monk episodes I guess. Imagine if Monk went to India and had to survive on water there or something like that.
