Welp, they've done it. The Honest Trailers series from Screen Junkies is one of my favorite YouTube shows. It's a great series on an otherwise somewhat boring channel. They've done some collaboration with writers of other Marvel movies where they watch and critique the Honest Trailer for their movie.
For some reason they've gotten the attention of filmmakers, somewhat positively, while other series like Cinema Sins has gotten mostly jibes and criticism. I like them both, but if I had to choose, it would have to be Cinema Sins. I think their videos are funnier and more in depth.
However in this episode of Honest Trailers they collaborate with Ryan Reynolds as Deadpool, in the classic 4th wall, wisecracking theme of the original movie. It's part sell-out, promoting the release of the DVD and Blu-ray, and part hilarious. Check it out if you haven't already.
