Castle - Staring Nathan Fillion

I wouldn't have watched Castle if it weren't for Nathan Fillion, and I probably wouldn't have liked it if it weren't for him either. Without him this wasn't a bad show. The female cop was fine, Castle's family was interesting enough and the plot was pretty routine.
That said I think that Nathan Fillion was perfect casting for this show. As "A 8 year old on a sugar rush" character he is almost perfect. He shows enough that you suspect their's more to him while keeping it fun and I bought that though he was childish he was also a pretty good detective.
As premiers go this one was solid and I'm more likely to watch it than any other police drama since I like to keep up with the firefly crew.
