There was always something missing from Whedon's version. The plot felt messy and the two-hour film seemed to drag on as it went from fight scene to fight scene. Despite being twice as long, it felt like almost no time passed while I watched the Snyder cut. Storylines that seemed out of place or nonsensical in the original suddenly had backstory and clear explanations. I actually CARED what happened to the Justice League at the end of the Snyder cut and was ready for more DC films. After watching Whedon's version, I just wanted to cleanse my palate with a few Marvel films since his felt like a shoddy imitation.
Not only did the overarching story make more sense in Snyder's version, it made me want to see his version through to the end. No fast-forwarding, no breaks. I needed to know how it all ended.
