I watched fanvids for years before I read fanfic, and I haven't come across many good ones recently so:

1. Any fake trailer; it can be AU or canon-based, about anything. I'm cool with completely new trailers (like Castiel: The Motion Picture by badhalo) or fusions that use audio from a different movie (like Pride and Prejudice Destiel Style by seriouslymirah).

2. Music videos, focusing especially on Cas/Dean or Sam-centric, but if you just have an awesome vid you want to rec please do.

Self-recs always welcome. Thank you!

ETA: I just wanted to thank everyone for such awesome recs...so thanks! :)
