Yeah, I stomached the 2.0 stuff even though it's humour wasn't my cup of tea since it came with some nifty trials. The 3.0 stuff irritated me as a huge FFIX fan since a character like Vivi deserved better than to be associated with pure comic relief in my opinion. It worked for Ultros and Typhon since they were gimmicky characters to begin with...
Might be an unpopular opinion, though. A lot of people seem to love the quest chain.
I was left with the impression that it should have ended with 2.0 though. A lot of the jokes were exactly the same.
