First off, it's just this ugly distracting lime-green thing UI that follows you the whole game. You get maybe five seconds to run before you go back to your too-damn-slow default speed, and it's always beeping(why does everything freakin' beep in this game) because our Hero of Time can't run 6 seconds without stopping. You start playing this little meta-game of "I bet I can run to that platform/area/door before my meter runs out and the beeping starts again", and this goes on for 40 hours. And it's not just basic movement, but rope balancing, underground crawling, all kinds of things are now that much slower to do. I mean, say what you will about TP but at least I could roll wherever the hell I wanted to through this way too big game.
It's one of those games that has a lot of brilliant moments and areas and things, but it just pecks away at your sanity with so much tedious shit. The slow text-speeds, Fi's obvious comments, the stamina meter's unnecessary limit on how, the dowsing, the superfluous motion controls(underhand bomb throwing? Swimming? the bird? ugh), so many damn fetch quests, the too thin story stretched out to forever and I stopped caring halfway through, the segmented overworld, the repeat bosses, the obvious filler sections...you just throw your hands in the air and say screw it after awhile.
The 3D series has just gotten so bloated and packed with dubious design decisions, longer cutscenes, more filler and assorted pacing issues, it's actually pretty frustrating. It makes me think that console Zelda might never trim that fat in favor of a faster-paced gameplay driven experience again.
But that's what LttP2 is for I suppose
