Personally, I never liked the entire Szayel fight until Mayuri came in and said "Bitch, think fast~ Oh wait..."
The two stooges act idiotically.
The other two stooges act idiotically.
Ishida and Renji were weak to being with.
There's probably going to be more slapstick humour (I'm going to probably cringe at every single crack for the next 20 episodes).
The fight itself in the manga took forever to end (ie: Ended only three chapters ago).
And the epic moments (ie: OH SHIT HE ATE HIM!!) will probably not be enough to counter whatever fail that's going to be in it.
