First of all: Bruce was hunted by the military and lost his life for years. Jen cited a lot of things, a lot of his traumas, so he clearly, as suggested in The Avengers, knows what it's like to be angry all the time, "always angry", as said in the movie.
This felt fairly par for the course in the MCU's treatment of Hulk things: Take an interesting story, and fill it with a bunch of MCU nonsense. Jen gets her powers because a spaceship made her crash, not because she was a shot. There isn't interesting psychological ramifications as to why she can be She-Hulk and have no other identity, just like there isn't any real reasoning for why Banner and Hulk have separate identities. Needless comedy.
The virgin Captain America discussion was dumb and pointless, particularly because his virginity is irrelevant and he clearly was married to Peggy, so he certainly never died virgin even if he didn't have gross, out of character sex in 1943 or whatever.
I didn't hate it, and I'm torn between whether or not I think it's better than the Hawkeye first episode, but I think all the other MCU first episodes, besides Hawkeye maybe, were stronger written and/or more interesting. Preferably it can get away from the MCU gibberish and feel stronger, to me, like Hawkeye did by the end, and not like WandaVision did by the end.
