My well written review got eaten so quick summary of thoughts:

-nostalgia bit me here
-fire emblem works because of the characters AND gameplay
-the look is less edgy(though still bright) than the original, smoothed out in 3D
-difficulty is all over the place
-feels like you solve dev strategy puzzles vs actually strategizing
-goofy(but not goofy enough)meaningless war is a bad plot
-its fine but I'm not going to waste more time on it.
-slow as hell, lots of waiting and huge time sink when you lose especially.
