Not great, Bob. None of the comedy landed for me, with the main running gag ("Was Captain America a virgin?") just being a punchline with no build-up at all: it might have been funnier had Bruce been telling Jennifer about Steve Rogers throughout their time together to teach her things and her takeaway was that he must have been a virgin. That the entire joke is the idea that it's supposedly funny that Captain America might not have had sex shows how little the writers understand humour beyond quips (which are about wit and timing, of which the Captain America schtick had none). Bruce constantly doing Superhero Sad Face about Tony Stark was clumped in with no finesse or purpose beyond 'Remember how Tony Stark died in Infinity War? Marvel universe, everyone!' The female empowerment stuff was as clichéd as it comes, not showing empowerment through Jennifer actively achieving anything - in fact, she didn't even want to be She-Hulk - but by her reactions to the generically odious men around her. While a woman dealing with men being condescending or dismissive of women can work in and of itself, the stuff here is the most by-the-numbers, one-dimensional material possible: men telling her to smile, trying to take credit for her work, explaining things to her, being pushy and disrespectful outside a bar, etc. Exactly the same stuff, almost to the letter, from Captain Marvel and Wonder Woman 1984. Even if we momentarily take it for granted that these are every woman's shared experiences, as the show seems to posit, it's still become tiresome cliché in storytelling terms and is often relayed in didactic generalities (fear and rage are every woman's baseline emotions, apparently).
As for the story itself, the 'hang out with Bruce' conceit might have felt more substantial had there been any sense of progression, instead of Jennifer just repeatedly showing Bruce that she didn't need to be there and thus communicating to the audience that it was a waste of time, or even were the moment-to-moment material any better than undercooked jokes (when they were discernable as jokes) or weightless action in cartoony CGI. The only thing that mattered in the flashback was that Jennifer got infected with Bruce's blood, and perhaps his assertion that his door is always open, assuming he's coming back. In other words, around 90% of the episode could have been cut and little-to-no difference made to the weirdly abrupt ending: Jameela Jamil bursts into a courtroom and needs thumping! Why? Well she IS Jameela Jamil, but within the episode there was no reason given beyond her being there for the sake of giving Jennifer a badly contrived reason to reveal her Hulk-self.
Long story short: more badly written Marvel time-wasting with bad CGI, worse clichés and 'jokes' barely recognisable as such.
