I actually enjoyed PoP2008 quite a bit when I played through. Sure, combat was a series of really annoying quick time events, and at the end it was essentially 'push button, win game', but it was gorgeous, and the soundtrack was excellent. I actually had no problem with the voice acting.
Things I didn't like about it were:
1.) There was no prince. Literally. There was a princess, but unless she was sporting some extra equipment that we weren't informed of, she doesn't quite fill this requirement.
2.) There was no Persia.
3.) Combat.
4.) The epilogue. The DLC had me raging out like you wouldn't believe. The main enemy kept switching between the Hunter and the Warrior, and only those two. Ever. You have to fight this bastard like, what, 6 times? I was so sick of his face. I beat it, just to have the ending, but CHRIST. Come on!
I still don't get the hate really. I mean, I loved the hell out of Sands of Time (Warrior Within was crap, I don't care what anyone else says. They killed the series for me with that emo trash.) but I could accept that Ubisoft wanted to do something new. Mind you, I don't really consider PoP08 a Prince of Persia game. It's just a Middle Eastern themed fantasy platformer that rips it's mythology from Zoroastrianism that they tack the title 'Prince of Persia' on to sell it. I still liked it. I honestly hope they don't completely drop the storyline. Cliff hanger endings that drop off into nothing suck.
