Yeah. It's certainly not universal across the board, but you might enjoy this particular Snyder joint if you have a history of liking his other movies as well.
RT is a strange animal. I can see where the inconsistent "review algorithm" or whatever you want to call it can drive fans batty.
I also don't think it's accurate to compare MoS to a movie that was out a few years ago like SM3, without taking into account the increase of publications and blogs and other reviewers that are counted on the Tomatometer that weren't in the past.
Also, I admit I have a greater affinity for Marvel movies at the moment. Years ago, I loved the DC properties though. I'll admit that I love Captain America a lot, flaws and all, and I do sort of see Superman and Cap in similar veins to each other. That being said, I'm still open to some reinvention of either character, the only thing I ask is for an entertaining movie to service the reinvention
