Add Gaia's Navel from Chrono Cross to the list for me. Everytime I play the game, I loath this part because it feels like such a waste of time. Basically you just run around beating enemies until the boss finally decides to show itself. It isn't hard or tedious in any way...it just kills my momentum.
And I have one for Chrono Trigger as well. The Lost Sanctum content in the DS port was a huge pain in the ass. You can get some good gear, better than what was previously the best...but the entire sequence was a chore. I can appreciate what they were trying to do (give a glimps into the Dinopolis timeline referenced in Cross), but they went about it all wrong. It was just a series of tedious fetch quests that required a ton of back tracking, that added nothing to the plot overall.
