I tend to agree. People don't like the 'theming' of this new version, but what was the theming of Centorium? It had a cool entry sign, but the interior looks like what I guess seemed like an ultra-contemporary department store at the time it opened. Other than going back to that nostalgic 1980s mall vibe, I don't quite know what those complaining want a 2021 version of the store to look like. Even the complaints about Mickey being represented in the store seem a bit off base looking at Martin's tribute video which shows character figures very liberally spread through the Centorium. The name is a bit meh, but also better than MouseGear.
All that said, Centorium is a super cool name that they should have brought back!
