That there are several real male and female characters in The Big Sick is a tribute to its writers, the real life couple whose story is presented in the film. There are very few caricatures in the film. The ones that might qualify are so deftly handled, it just feels like a person we know and not a punchline waiting around to be had.
It's not that I hate this film. It's got some good, albeit disconnected moments. The task of entering the DC Universe mid-step means it will necessarily be different than the origin story heavy Marvel Universe. A used universe is fine with this reviewer. It just shouldn't have to require one to watch Blade Runner to lighten the mood afterword.
