So I just saw the first episode of The Mentalist...
I couldn't help but compare it to Psych. Unfair maybe, but I was thinking of Simon Baker, "well he tries, but he's no James Roday." ;)
Seriously though...I couldn't get a handle on the Jane character. He tries to be smart, he does that okay but comes off a little annoying; he tries to be - I don't know the word, arrogant maybe? - but since it's not a comedy, the character kind of just seems like an ass; and then there's a bit of recklessness near the end of the episode, which really doesn't seem very smart. (Particularly since he seems to have had more than enough time to create a plan and set things up.)
I guess my main problem with it at this point is the character isn't very likable - it's not that easy to sympathize or relate to him. Maybe it gets better in the later episodes?
Oh and I'm posting here because I don't want to run into any spoilers in the Mentalist boards.
