Hated the Max Payne 2 ending. Actually, I really hated everything about that one. The origional, though, was probably the best FPS ever; it certainly had the best storyline by far. So many intricacies, a powerful subplot about Ragnarok, plus a beautiful, Film-Noir-meets-Gothic style that is still a joy to experience. The ending was my favorite of all time, as well; absolutely cinematic, like the game itself.
Then Rockstar comes along and completely ruins it. The second had an atrocious plot, completely devoid of the beauty of the first; the style was a sick parody of the first; and none of the characters turned out right.
The gameplay was marginally better, admittedly, but it also felt stale and much less origional (oooooh, goody- more bullettime... whoop de [woo].) And I can't even remember the ending; frankly, I really can't remember much of what led up to the ending, because the plot had lost all interest for me so long ago.
Kinda like a real movie sequel.
