Only certain pages look right, the rest will be messed up. This userstyle works best if all you care about is browsing anime while using a free account. (i.e., you ignore the community, forums, store, news, front page, etc.)

I highly recommend using adblock in addition to this.
Videos are stretched to encompass the entire width of the browser. This was the original purpose of this style.
A bunch of unnecessary elements (in my opinion) are removed.
Search works but it looks best when browsed from http://www.crunchyroll.com/videos/anime
Comments are hidden right now. I may make them visible again if I can find a good position for them.

There's much to be desired considering the pages that look off, but I find this sufficient for my needs.
