10 worst CGI moments in the MCU, ranked
1. Swapping powers in the Secret Invasion finale
If you never really enjoyed Secret Invasion through its six-episode run, then this was the final nail in the coffin. On paper, a confrontation between two Super Skrulls who can control every MCU superpower in existence sounds like a terrific way to end the series. But the VFX stands out so much throughout the entire fight that the result is... less than stellar, to put it lightly.
To be fair, as the sequence goes by, things start to look somewhat passable. But the scenes where "Nick Fury" grows a Hulk arm and punches Gravik at the very beginning and when G'iah grows a Drax arm, are some of the worst CGI moments in the MCU as a whole (if not, the worst). By this point it has become evident the series' budget of 211 million dollars wasn't enough to ensure it would have a good VFX quality. So perhaps it's time for Marvel to rethink its strategy and leave the big-comic crossovers to a 3-hour movie instead of a 6-episode series. A smaller run-time would result in fewer CGI shots needed to be done, and an overall higher quality for the ones that do make it into the final cut.
It's just a shame that it's already too late for the Secret Invasion comic-book event.
