It is James Gunn so if you liked Guardians of the Galaxy and/or The Suicide Squad (the good one without Will Smith) then I’m guessing it will be fun as there is a lot going on in the trailers and it includes things from the comics that are normally excluded from superhero movies for being too ‘weird’ like a super powered dog.

It might not be as popular with general audiences as other versions for the reasons you mention whether it is good or not.
