12. Spider-Man suit in Homecoming
There's a major problem with Tom Holland's suit in Spider-Man: Homecoming in that it looks too perfect. One glance is enough to note Spidey's costume has no wrinkles or stitching on it. Instead, it perfectly wraps around Peter Parker as if it were glued to his body, making it appear almost like skin. While the lack of those details does give the web-slinger a "smooth" look, it, unfortunately, prevents him from feeling like a real, tangible hero.
Take the opening swinging sequence of The Amazing Spider-Man 2 as an opposite example. When Andrew Garfield's Spider-Man is free-falling, we see how air flows in his suit forming these moving "wave" patterns across its back. Those little details are nowhere to be found in Homecoming, and they make a big difference when it comes to making CGI look realistic.
As time went by and more Spider-Man movies were released as part of the MCU, the visual effects team was able to find a better balance between a good-looking suit and a realistic one. But that doesn't prevent our friendly neighborhood hero from swinging its way onto this ranking thanks to the Homecoming suit.
11. Moon Knight car chase scene
Moon Knight is arguably one of the best MCU series ever made, so it's unfortunate that its CGI wasn't on par with the rest of the series a few times. Most notably, we have to highlight the car chase scene that took place in the first episode.
There's something about this sequence that feels like you were watching a pre-rendered scene on a video game. Especially when the action focuses on the cars crashing into each other. They sometimes feel too "bubbly" or weightless as opposed to how real vehicles would behave on an impact. Besides, there's something in the lightning that alerts your brain to the fact that this whole sequence was made on a computer (which, you know, most of them are but it's better when you aren't able to notice).
