Here is an unofficial list of all anime available online for free legally, the poster tries to keep it up to date.
I don't have netflix so I don't know what anime they have.
Consider watching something that is currently airing. The spring season of anime has just starting, and it's always exciting to see an anime as it's airing before everyone decides to form an opinion about it. Of the one's that I am watching, I would recommend Kids On The Slope. Not really related to Mushishi, but I think it's looking to be one of the best anime this year. It's available on crunchyroll.
Prepare to be bombarded with anime suggestions, but in the end just watch what you like dude. :)
