The Pixar Theory
This is a theory that I discovered a while ago from John Green, the author of The Fault in Our Stars. This theory suggests that all of the pixar movies exist in the same universe. All of the movies are put into chronological order, and put on a track for a massive war. If this sounds interesting to you at all, you should definitely check it out!
The Tarantino Universe Theory
For all of the Tarantino fans out there, this is for you! This theory states that all of Tarantino's films take place in the same universe AND that Tarantino even wrote in an alternate world history (if you've seen Inglorious Basterds, you know exactly what that entails). The link I've included shows the universe theory, a commentary of the meaning behind Inglorious Basterds, and the theory of what's in the famous briefcase from Pulp Fiction.
Rifftrax
Rifftrax is commentary at it's finest. The crew at rifftrax record hilarious commentary to popular movies as well as forgotten (mostly awful) B-movies from previous decades. If you are remotely familiar with Mystery Science Theatre 3000, then the cheesy, even campy humor is right up your alley.
CinemaSins
Out of all of the items on this list, this might be the pickiest of them all. CinemaSins is a commentary that rips films apart. A film's amount of "sins" are tallied, and the film is given a score based on that count. But it's not just films being put to the test- music videos, video games, and even commercial brands. What's said at the top rings true for the whole channel: No movie is without sin.
