It's chaotic from the onset. It has continuity flaws throughout and the James Corden thing is a bit too much throughout.
The screenplay was apparently written by a stoner, with giant gaps in the story arc that have to be described since they are far from well written.
It's apparent that much was improv, because the dialog didn't match the teleplay.
Further evidence was when actors were improvising, scenes that should have been short were tedious.
In short, it's two hours of my life I'll never get back and hope to forget.
