He has some great ideas, but he really needs a proper showrunner who can put those ideas into a script that ACTUALLY MAKES SENSE. As it stands right now, Matt Smith is going down in history as my least favorite Doctor, not because of Matt's abilities or acting, but because his entire run was encumbered by Moffat's bad writing.
Honestly, I always feel at least a little sad when a Doctor leaves (I actually teared up at Tennant's departure), but by the time Matt Smith got around to the regeneration scene I was looking at the clock wishing the blasted episode would have ended 30 minutes earlier.
The thing is, I love Doctor Who. I have for almost 30 years. It's one of my last few passions. And to watch Moffat crap all over it the last few years has just been agonizingly painful.
