If the rumors about the anime are true, the description is just the tip of the iceberg haha. It apparently has a lot of stuff that you'd never think a mecha anime like it would have. Just like how Madoka Magica started looking like a normal magical girl anime and ended up being something that's a deconstruct of the genre and a slightly dark anime. :p
And ahaha, I can relate. Why not watch Dragon Ball Kai, though? It is a remake of the Z series with fixed pacing issues (no more 10+ episodes for Goku to land on earth to battle Vegeta). Might have a little censorship, though, but I think it'll save you a lot of time. I'm sure you won't miss anything - it just cuts out a lot of padding that was originally there in the anime for it to not catch up to the manga. :p
