It was kinda crap, but the fight scenes were good. A bit hurried, and the voice actors weren't exactly ideal for some of the characters, and most of them sounded the same.

Vincent probably doesn't sound like that, and has more a poetic twist to his voice. Sephiroth definitely would sound like that. Tifa spoke worst than Aerith, and sounded so robotic. Barret was ruined from the start, when you hear him on the cell phone. Yuffie was what you would expect, and Cid just looked weird. Cait Sith isn't Scottish or Irish, and how would they programme that voice for him? Reeve wouldn't do that.

Reno said a couple of stupid lines, which weren't funny. He isn't supposed to be a comedian, he's the casual guy who everyone loves. Don't even get me started on how they messed up Rude.
RedXIII was quiet, and Kudaj's gang were totally emo. "Where's mum?" I heard that every 2 minutes.

Best part was when Sephiroth came, and livened it up a bit, but the unbelievably and far-fetched strength of Cloud, beat the holy hell outta him.
