dragonbeast: in all honesty, I've never even heard of it
Gilozard: It was interesting, but not a must-watch anime IMO. Post-apocalyptic, weird-critters-killing-off-humanity, a lot of it was fairly typical of the genre.
dragonbeast: here are some i have watched, probably forgetting a bunch
FMP! + FMP! TSR + FMP! fumoffu?!
Gurren Lagann
Gundam 00
Evangelion
Eureka 7
Aldnoah 0
Gilozard: Gundam Wing is pretty good, and a bunch of the other bigger Gundam series. But avoid the one that's basically an excuse to hold tournaments between horrible ethnic stereotypes, it was really bad - was it Gundam Build Fighters?
G Gundam is one you're thinking of. It was a big departure from the other Gundam series and is much more reminiscent of Dragonball or Yu Yu Hakusho since it's all about individual fighters with semi-magical powers in fighting tournaments, just with giant robots added. It is kind of fun to watch if you enjoy the corny "Believe in Yourself" dialogue and themes.
It may have been mentioned already, but FLCL is a short, four episode anime that nothing short of crazy awesome, emphasis on the crazy. I haven't watched much anime or sought out new shows in a while, but I still rewatch that one because of how I've never seen anything like it.
