She-Hulk begins with Bruce Banner in human form and with a cast similar to his appearance in Shang-Chi and the Legend of the Ten Rings. Still disabled after his use of the Infinity Gauntlet in Avengers: Endgame, Bruce is injured in a car crash while in human form, resulting in his blood coming into contact with an open wound on Jennifer, who was driving the car. This is how She-Hulk is born. That in itself isn’t a problem, but when She-Hulk awakens in a lab built by Bruce and Tony Stark, she finds a Smart-Hulk fully healed from the damage done by the Infinity Gauntlet in Endgame.
The healing process is done off-screen, with a simple explanation that Jennifer’s Hulk blood has a special quality that allows Bruce to become whole again. His injuries are reversed so he can have a fun practice montage with Jennifer, but Execution feels unconcerned about how it makes the MCU feel like it’s not on assignments; a lack of consequences that leads to stories that aren’t all that interesting for that reason. Up to this point, the MCU has kept audiences invested in its characters by offering real growth and development.
From Tony Stark’s sacrifice to Steve Rogers’ decision to retire, there was a real sense of closure surrounding Avengers: Endgame. Unfortunately, the creative choice to heal Hulk contradicts those sacrifices and feels eerily similar to what you’d read in a Marvel comic.
