Well, I'm glad we can all agree he's a bit disappointing. XD
There probably is indeed something metaphorical going on here, because otherwise he's just remarkably a childish jerk, which is an odd note to end on. I feel like it's a bit lost on me though. Too much metaphor, not enough grounding.
Either way, purely subjectively speaking, it sucks a bit to have such a lovely dreamy sequence end so flatly like that :/
