First off the premise of the movie is thoroughly confusing, and it's never explained exactly how these 2 continuities are meeting. The movie implies this is a universe where Mystery Inc has always existed within the DC continuity, however this causes a large issue in that if Mystery Inc exists in a world with supers, why do they still stick to the "there is always a reasonable explanation" philosophy? This whole issue ripples through the rest of the movie and causes it to be hard to get any investment.
The best part of the film is the character writing, mostly from Mystery Inc as all the characters are fun and provide a laugh here or there. Batman is alright too but not too interesting. The Riddler was also quite good, I thought it was strange how his plan in the opening was to just take money in a very short sighted and cartoonish way, so the reveal that it was a fake riddler so the real one could disguise himself with the main cast was a great reveal. Only problem is he has minimal motivation for making a super weapon to destroy anything in gotham and I wish they put more thought into that aspect. Aqua-Man was also in the movie for some reason and was completely insufferable, theres this one really tonally off part where he makes a joke out of Jason Todds death to Batman's face, like what the hell.
There are many, many questionable aspects/plot holes in the movie. Like how Batman states the detective team is "secret invite only", yet they let Plastic Man on who has zero qualities as a detective. Or why characters keep having to clarify if Batman is referring to "the REAL batcave?", like, it's not like theres a batcave on every corner what batcave do you think he means! Or how Clayface can fly inexplicably, just to name a few I remember.
So yeah, pretty alright. If it weren't for the impossible premise taking me out of the whole thing it'd probably be a high 6 or low 7 rating. Give it a watch if you don't care about that sort of thing.
