It's been absolutely epic - not only is the running time of the whole thing over 50 hours, but the editing has been great, and the experience of seeing the whole saga unfold in a timely fashion has put a whole new spin on some much loved films. There are times when you're jumping from film to film, but it's been edited so well that it all makes sense and forms a cohesive narrative spanning multiple characters and plotlines across the multiverse (or at least it did to me, who admittedly has seen the MCU films a few times before).
I fully credit FireMerkStudios for his Dawn of Thanos idea, and I openly cite some of his content as my source. He has attempted to do exactly what I am working on here, though he cut out MUCH more than I did. Whereas he aimed to do a series of short chapters, mine will be 6 full length movies in a Star Wars saga-esque presentation. In my Dawn of Thanos re-edit, I will be combining ALL Marvel content into one, refocused narrative about the Avengers vs Thanos.
