I think he has run the show into the ground personally
I agree!
Whilst I think his RTD-era episodes were fantastic (I really liked GITF), his show-runner episodes have been highly sub-par. With the exception of The Eleventh Hour and The Pandorica Opens, the rest of the series has been terrible (Amy's Choice was fantastic, though not written by Moffat). And I have to say, it took me 3 viewings of The 11th Hour before I really liked it. Perhaps it's because I only watched it once, but I'm not a huge fan of Vincent and the Doctor. The Hungry Earth 2-parter literally almost sent me to sleep - the most boring NewWho eps ever for me personally (I haven't seen the Classic series). Despite TPO being great, the Big Bang was really quite terrible - how does a plothole as big as the Doctor letting himself out of the Pandorica get past the initial script-stage?
Completely agreed. The Big Bang was an incoherent mess. I actually enjoyed The Pandorica Opens, and The Eleventh Hour was...well, when you compare it to other intros like Rose, Christmas Invasion/New Earth, Smith and Jones...it looks pale with very little plot.
