The battles in the Sol System, starting around episode 17 are epic in some ways. Episode 21 is probably the best if you are into space combat. If it is raw emotional story material, that picks up around there as well. Yamato 2202 has a problem of putting in material that doesn't make sense...at the time, that will come up again near the end to make the things that happen make more sense, or not seem like they just pulled a solution out the author's butt. Things are in place, or at least seen before hand. Just they aren't clear what they are or are for until later.
