Eh, it's almost there...
First off, this premise is tired, and has been done before. There was Captain N on tv, and Metal MAverick has a similar series here on NG. That said, I didn't die watching it.; it held my attention the whole time. I like the voice acting, though the sound quality was bad and scratchy. It had a humourous tone, but wasn't really funny. The animation was also farily lackluster, though the art was decent.
I'll be watching future episodes all the same, but there's alot of room for improvement.
