I get what you're saying. Just seems there's this hive mind these days to shit on brawl's texture work.
Brawl Mario Imo, I thought look much better with the denim overalls and Dark colors compared to Smash 4 in gameplay.
I thought Brawl's goal of going towards the more grounded approach in character design was a step in the right direction coming from Melee's vision in pushing the characters that had more detail compared to most games at the time.
People say there's more coherency in Smash 4. But there was also consistency in Brawl as well. At least in Brawl there was a tendency in giving characters added detailed across the board. If Brawl would have been given the HD graphics and lighting treatment it would looked good just as well.
