Owain or Lucina. Tharja is a creep. Chrom is the generic army leader. And Robin is hard to enjoy when, while s/he helps through the enitre game, the story doesn't shift to him/her until the end of the game and it isn't that long.
Lucina is a great character who goes through so much development and I really don't see why people call her bland.
Owain is an over the top theatric character who has a heart of gold. And again don't see why he gets the hate he does.
I voted for Chrom just because his character has given me the most laughs.
...And Robin is hard to enjoy when, while s/he helps through the enitre game, the story doesn't shift to him/her until the end of the game and it isn't that long...
I feel just the opposite. Robin's contribution was perfect before the end. The "just as Keikaku" monologue was somehow amazingly irritating to watch, especially as the MU is supposed to be the player's avatar. If they intended the player avatar to have such autonomy as to concoct such a scheme without the player's awareness, why even pretend Robin is a player avatar?
The plan also worked a little too perfectly for how contrived it was. I feel IS should have kept the Sun Ce / Zhou Yu thing going between Chrom / MU rather than turning MU into Batman.
