Scott Pilgrim worth it?

Since it's on sale this week thinking about getting it.  I tried the trial awhile ago and thought it was fun, but heard it was very short.   How does it compare to Castle Crashers, especially the online community?    I love Castle Crashers but everytime I try to play online multiplayer I can't get passed the lobby 90% of the time due to games not starting or getting kicked for no reason.   I can only guess it's because I haven't beaten it 10X+ with maxed out characters and nobody wants to play with a n00b.      Since it's only $4 I'll probably go ahead and get it but just curious of peoples opinions on it. 

Actually, its pretty good. Feels like a great old arcade side scroller beat'em up. It be a tad repetitive but it's a good game. I would get it since it's on sale.
