Stuff I've liked over the years:
1. SDF Macross (not the robotech adaptation!) - the animation has aged, but the whole Macross formula is gets established in this series (valkyrie fighter, idol singers, love triangle = macross)
2. Tetsuwan atomu (Astroboy)
3. Gatchaman - (Aka Battle of the Planets) - I always wanted to be Jun/Princess - it's aged terribly over the years as well.
4. Ranma Nibbunoichi (we really should poll how many trans people love this one *lol*)
5. Neon Genesis Evangelion (the super post modernist anime!)
6. Bishoujo Senshi Sailor Moon (not the DIC adaptation either!) - Malachite, the whole point about Sailor Moon is Usagi's pure heart overcoming all
