But in the spirit of the post..
I dont, generally. I enjoy playing the game more than watching an animation I've seen enough to be boring. If its a character I havent seem much of (LF or something) I almost hope I GET fatal'd so I can see them because its usually pretty awesome the first couple times, once the shine has worn off though, it ceases to be fun or interesting and just makes it take longer to get back in to another game.
Occasionally after a long set, i will fatal the final game if I win it, since it kinda caps the series.
