Oh you want an explanation? I was reading through the RT's reviews yesterday, and lots of them (not all) made comparisons to Marvel flicks, in my honest opinion, it's unfair to compare an established "universe" that has been running for years with something that's just started, it's also unprofessional to derive from talking about the movie to compare it with something else, a movie should be reviewed on its own.
Umm. Ssimilar things will be compared. Fox's movies are also evaluated. Xmen generally good. Fantastic 4 generally terrible.
Fantastic 4 was not great before mcu. Fan4 stic terrible after mcu. Original xmen trilogy good except x3 before mcu. First class trilogy good overall.
Deadpool good after mcu. Wolverine origins bad before mcu.
Movies get compared, but they fall or stand on their own.
The failures of man of steel, bvs, and suicide squad are transparent pretty objective and universal problems.
Bad scripts, bad characterization, messy plots, choppy editing.
These are things that are bad in any genre.
