I would like to play all the bosses again sometime...but not necessarily the whole game right now, and certainly not the Water Temple!
I hope Majora's Mask treats you well -- it was significantly better when I tried to replay it last year than it was when I first played it. I couldn't finish it since my game stopped saving properly, but it's redeemed itself.
