Last Generation Hero
This is my favorite anime. It's also the anime that got me in to anime. The animation's gorgeous, the art and style's classic mecha and spaceship design at it's finest. Gene and the crew are fantastic and fun without a single point of failure (Well. Coulda used more Aisha, but everything could use more Aisha).
I'll skip going on at length, and gods only know I could, but this adventure of leaving boyhood behind, of finding your place in a sea of stars... it's worth your time straight up. It can be a bit hard to find but it will reward your efforts. It's also worth noting the dub's pretty good.
