Well let's hope so, but until the critics start to do that then I will remain pessimistic.
Unfortunately I don't think the numbers from RT support this theory.
After 6 movies, DC has an average audience score of 73.5% and average Audience rating of 3.88/5
Meanwhile after 20 movies Marvel has 83.25% (13% higher) and 4.07/5 (4.9 % higher).
If critics are influenced by their audience then their ratings should somewhat reflect the audience rating right? Instead here are the stats:
DC: Average tomatometer 51.17 % - average critics rating 5.82/10
Marvel: Average tomatometer 84.05 % (64% higher) - average critics rating 7.2/10 (23% higher)
The averages show that the GA indeed like Marvel more than DC, but not by much. It's the critics that are massively favoring one over the other.
Of course 6 movies is a very small sample, and BvS and SS really skew the average tomatometer, let's see how the averages change when DC has more film under their belt.
