Why did everyone forget about Sonic Superstars after a few months of it came out? And why is it so hated?

While the rest of the current Sonic games like Sonic Frontiers which will complete its third year this year are mentioned and played, Sonic Superstars is not talked about now and nobody plays it, and I also noticed that this game is very hated, why? I don't see it as a bad game at all, it was fun despite its flaws, maybe the reason for hating this game is its exaggerated pricing, what about you guys?
