EGOTISTICAL TOUR-DE-FORCE 

Nonsensical Cinematography term used when you don't understand a single thing about the movie, so you are obliged to say something faux-meaningful about the director. Originally used in late 1980's in Limerick, Ireland by amateur would-be film critics before spreading urban areas and thence internationally (BMC)

"I felt the film used a mishmash of several differing genres and tropes, but my main comment would be that for the director, it was an egotistical tour-de-force'

Aaron Peckham was a one man tour-de-force, creating UrbanDictionary.com and forever changing the english language all before he turned 30 years old. Unfortunately it was all down hill from there.

tour de farce 

a performance covering a ridiculous set of non-sequiturs or otherwise wildly unrelated achievements and situations

The band's performance surprised the large gathering with a tour de force of popular (and some not so popular) music from the 60's, 70's and 80's. The variety spanned from Elvis to the Eurythmics, Black Sabbath to The Beatles, Mungo Jerry to Lady Smith Black Mumbazo, Santana to Simple Minds. Maybe it was more "tour de farce"!
