Okay, that headline is a terrible way to describe it. Here's the situation: some clever person has taken all scenes featuring Loki from all Marvel movies -- I'm talking Thor, The Avengers, deleted scenes from those movies -- then stuck them all together into a narrative structure therefore giving Loki his own goddamn movie.
I support this wholeheartedly.
The best parts, for me, is seeing deleted scenes and blooper reels being somehow integrated into the story. Pretty awesome.
Also, this thing is like two hours long. It's like fan fiction... in video form. This is the new vanguard of fan fiction. This is art.
