Mine would have to be Metal Gear Solid. I cannot stand that game at all. I can't even get an hour in to that game without turning off the console. I really just don't like the espionage gameplay of the series, and not to mention with every entry, they focus more on cutscenes than the actual game, and it's just annoying to walk 3 feet and get thrown into another cutscene after YOU JUST FINISHED ONE.
Don't even get me started on Metal Gear Solid 4. Worst $20 ever.
