Well, Shepard was always more of a player avatar than a character, so the lack of character definition is understandable. ME3 did more to define Shep's character than the other games at the expense of some dialogue options in conversations, which is something part of the fanbase had a big issue with. In typical BioWare fashion, it was up to the players to define Shepard's character.
