Half the reviewers not liking it is not a complete canning of the film though. Somewhere in the lower 30 percentile would raise an eyebrow when the audience perception is that it's good. You literally can not trust/defend RT, they are legitimate sellouts that have become a joke in their effort to attempt to avoid the joke of "All critics are contrarian 2deep4u narcissists" not realizing they have become that in the process.

I guess RT just has an unfair Twilight bias as well.

but to suggest they're anything other than a big commercial success because professional critics didn't like them doesn't make much sense.

Is anyone really saying they were commercial failures though? Forbes did publish a decent article detailing how the earnings don't necessarily indicate a commercial success, but that's about it. It seems clear that everyone is focused on the (decidedly, if not objectively) poor quality of the films and relative failure compared to Marvel.

Suicide Squad maybe, I haven't seen it yet. But MoS and BvS were no means bad at all.

Just because RT is "biased" against DCCU doesn't mean they're good movies. They're bad movies, bias or not.
