Black Panther — Killmonger Fight (2018)

Black Panther's climactic Killmonger fight undermines its groundbreaking cultural milestone with two rubbery CGI figures bouncing off mine cart rails, a jarring drop from the film's practical Wakanda sets. This 5-minute sequence, costing an estimated $10 million, suffers from a quality gap, symbolizing the industry's effects crunch. It remains the textbook case of rushed visual effects in a $1.3 billion blockbuster.
