Although not yet available to watch instantly, you can watch both the anime series and the live action movie through Netflix as an alternative to buying the DVDs yourself.
Currently the anime series is rated 3.6/5 stars and the movie is at 3/5.
I was also recommended to check out 3 other anime series. The first is Gurren Lagann which I saw and did enjoy. The next is Desert Punk, which at first I thought was Sand Land the anime but I had the titles confused. The third series is School Rumble. I actually had a wall scroll from that series for sale on eBay a while back. Netflix guesses I’m not just going to like it, but that I’ll really like it. Well we’ll see soon enough.
