The opening credits sequence of Deadpool & Wolverine was incredible, but it's a shame Marvel Studios didn't choose to copy one brilliant trick from 20th Century Fox's Deadpool movies for Ryan Reynolds' MCU debut. Deadpool & Wolverine was game-changing for the MCU as the franchise's first R-rated movie and as the perfect project to bridge the gap between the MCU and Fox's X-Men franchise. Deadpool & Wolverine quickly became one of the MCU's most entertaining installments, and the movie's inspired opening credits sequence set the tone immediately.
