2. Justice League
We can't discuss the biggest misfires in the history of superhero movies without discussing Justice League. For clarity purposes, I'm not referring to the Zack Snyder-directed version that came out in 2021 (that movie might have been long but it was the larger-than-life spectacle a Justice League movie should have been); no, this entry is solely reserved for the absolute disaster that was the 2017 theatrical version.
Directed by Joss Whedon (who stepped in after Snyder stepped away), the film is a complete mismatch of the two styles, desecrating the ambitious visuals of the previous director's vision with cheap substitute CGI landscapes, an awful redesign for villain Steppenwolf, and unfunny 2000s jokes that stood out like a sore thumb in a universe that had yet to produce anything with that kind of humor. The characters were misunderstood, the showdowns lacklustre and unmoving, and don't even get me started on the awful CGI-laden attempt to conceal Henry Cavill's mustache during the reshoots.
It's only when you watch the Snyder Cut that you realize how much damage the creative changes and the reshoots did to this movie. Everything about Snyder's version carried more emotional weight, gravitas, and power, and even though it was longer than it needed to be, it felt like what a Justice League movie should feel like.
The 2017 version, however, felt like the antithesis of that.
