I would go so far to say that everything past Legion's last scene was awful and of poor design. That was the last great and memorable scene of the entire game, and the last time that the game play approached anything unique and interesting. Some people dislike the reaper scene right before this for plot reasons, but frankly it was an interesting turn of events at the very least made a compelling, frantic, and awesome playthrough. I can ignore the concept that the reaper was being an idiot for the simple purpose of it being a fun scene.
But after Legion's last scene (No spoilers, dammit!), the game takes a massive downturn both in quality of storyline and variety of gameplay. It becomes nothing more than a slog fest after slog fest with almost nothing interesting happening in the storyline. The cutscenes were all unpolished, with the characters acting like a block of wood. The emotional tension that had been created up to this point was almost completely lost by rather laughable and unbelievable dialogue, and little to no reason for continuing after this point.
So really, there is a lot more wrong with the game than the "last 15 minutes". I would say the last 4-5 hours were absolutely abysmal and lazily done.
