Some great series mentioned here. I started watching anime when it first came over in late 70s and early 80s. So if you don't mind all the bell bottoms:
Star blazers. Aka space battleship yamato. All 3 series are on Netflix. There are 5 movies as well that are similar to series. And recent live action movie is amazing!
Gatchaman. Aka g force or battle of the planets.
Galaxy express 999/captain Harlock
More recently..
Full metal panic. All 3 series are good. Fumofu is hysterical
Basilisk. Romeo and Juliet if families were super powered ninja!
Macross frontier. Newest one. Fantastic animation
