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.
The 4-disc anime series is available here: Anime on Netflix and the live action movie is available here: Live action movie
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.
