I think the comics are awful too but not for those reasons.
The Jem characters are young women, the comic characters act like entitled millenials. There's too much "aren't they fun and quirky girls!!!" going on. Though I get that's the demographic they're aiming for and this is part of making a "modern update". It doesn't sit well for me.
Also there's so many references to other works, once in a while is fine but its creeping into unoriginal territory.
