I can see how it was lackluster. Even with it not being the main focus the way the characters are fleshed out you can't help but get attached. You spend time with them learning their history, hopes and dreams. Then it just ends with a black screen and a line of 'i spent the night with my *incert species here*, and thats it.
All the character building, getting so close to them and it just culminated to the equivalent of just skipping to the next day.
