My cycle has pretty much always been:
I LOVE THE DOCTOR HE CANT GO!!... who's this chump I've never heard of?... ugh this is terrible.... I'll give this one more episode... okay that was cool... OMG that was great... OMG I LOVE THIS DOCTOR... lather, rinse, repeat.
I only know the new Doctor from Attack The Block, which is one of my favorite movies, but I'm super amped.
All I can say is if you don't like this and won't even give a chance to disappoint you legitimately, you may have some unfortunate bias.
