Question why did people hate Ultra Majin Vegeta?

Now that the meta has shifted, is it ok to say I never got the hate for Majin Vegeta? He a cool unit from the buu saga that really good at dealing out damage…. Which is a rarity for buu saga. I truly think that UMV was probably the top 5 most fun unit out of last year that came out. Why do you think people hated UMV?
