IBS introduced very late.
I thought it was amateurish how, half way through the movie but immediately before a humorous plot point involving pancake's IBS, we find out he suffers from the condition. Should this not have been introduced earlier, or at least hinted at? It was like they thought of the tunnel/detonator gag but then thought they'd better shoehorn in an introduction to the IBS in the preceding scene.
And that is a paragraph I never thought I'd write.
