Why I Love/Hate Beethoven

I have a weird love/hate relationship with Beethoven (the composer, not the dog). His music enchants me, but very few of his pieces managed to escape my endless rants. He always finds a way, at some point, to upset me. I usualy define that point as the place where I think the piece should end -gracefully- but Beethoven disagrees and goes on with an additional movement to my annoyment.
