No spoilers please 
Castle has only recently begun to air in the UK, and so far I've only seen the first three episodes. I find it diverting, if a bit generic, it's main strength so far is the casting, especially Nathan Fillion who's always good value. That said I find I enjoy the Mentalist much more in the vein of smug smart arse assists straight laced cops!
Castle seems to have a lot of fans though, so I was wondering if it grows beyond it's rather thin premise?
Perhaps I'm expecting too much after just a few episodes but there was a lot of hype!
