This should probably be in the Spoilers section.
As to the question...all I have to say is that to me, the ending (story-wise) was lackluster. Felt incomplete, unfinished, and emotionally unsatisfying.
I didn't think it was horrible or completely wrecked, it was just...unsatisfying. The switch from being a 'party' with companions to suddenly being solo and having no clue, no idea, where the others are was too abrupt. You spend all this time building up your characters and turning them into Jedi etc. only to find that it was all for 'nothing' as you don't get to use them in the final battles.
Some kind of better explanation/reason for that would have been nice, at least - as some of the ununsed cutscenes of the NPC's wondering where the Exile went etc. would have provided.
Edit - I know the whole 'exile has to do things alone/stand alone' arc, but that isn't my point
