It kinda lacks conflict and a narrative. We can't really compare RT scores when it comes to DC and Marvel because RT always rates MCU movies highly.
Rottentomatoes doesn't GIVE
a rating to any movie. RT is an aggregate site of individual reviewers and as such your are suggesting that their is collusion amongst an entire group of reviewers either PRO Disney/Marvel or ANTI Warner/DC which doesn't explain Wonder Woman getting a positive review aggregate of 93%.
For what purpose would over 400 reviewers decide to collectively and allegedly reward Marvel and then punish DC because of Narrative and Conflict?
The 60% to 65% is the percentage of Reviewers that rated Aquaman Fresh. Their average rating though was 60% which is what you agree with regardless. The so-called Top critics are 50/50 and rated Aquaman at 54%. If you eradicated all of the Top Critics (BWAHAHAHAHAHAHA) from Aquaman's reviewers the rating goes up to ~67% which does kind of show that 38 Top critics are weighing down Aquaman 19/19 Fresh versus Rotten.
I still thought that positive word of mouth and the fact that Aquaman is a fun movie would enable it to garner a larger share of Fresh scores for the late reviewers but as of the last 10 reviews that have come in by date it has been 7/3 Fresh versus Rotten which ain't helping move that rating to Certified. :-(
I know it's an aggregate, but for whatever reason, RT critics are kinder to MCU films.
It’s not hard to figure out why: the critics are paid by Disney/Marvel! *eye roll*
Nah, it’s simply a case of MCU films being far less flawed and the majority of them are not only better than the DCEU’s output but even the “average” entries tend to be simply... good. Ergo, critics are kinder to them. Plus, Marvel putting out more worthwhile films than DC is something even ubiased critics (those that don’t have a preference for either Marvel or DC — scrape that, some ADMIT to being more DC fans) have consistently acknowledged. The Marvel Cinematic Universe basically set the bar high and their track-record is impressive. They’ve earned their respect.
Saying this will only spark the fanboy war, so that’s where I’ll leave things.
