The Star Trek movies and TFA were extremely similar in every way, Abrams is one of those directors who does certain things certain ways & you either like it or not, like Tim Burton, or Michael Bay.
JJ Trek films are two FX overweight sprawling messes with villains who are one or two dimensional. Full of lazy writing,. Kirk wakes up after dying after a couple minutes - that kind of stuff.
Star Wars is good fare, FX mostly under control and proportionate, very few silly scenes whilst still being effective with a genuinely wrenching plot twist that compensates for the typical death star battle. That's far tighter quality of filmmaking overall.
You couldn't have a starker gulf as to how JJ & Co have treated the two franchises.
