Properly amazing. It's basically a Jerry Lewis film.

Amazing first half, terrible second.

No plot.
No central character.
No antagonist.
No defined purpose for side characters.
No threat.
No three acts.
No jokes.
No punchlines.
No explanations.
No internal references.
No catchphrases.
No political polemical voice.
No melodrama.
No lessons.
No beginning.
No end.
One of the best films ever made.

Very tempted to click the "I've seen this film before" tab.
