I'll tell you why so serious
Wow! What a bizarre film! Unfortunately the few funny moments there were were quite overshadowed by it's completely weird and random vibe throughout.
As somebody who had not heard any of this before, it became a curious phenomenon to sit and watch a film and slowly have the realities begin to click into place.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.
