Am I crazy or is the Undertaker (at least in his american badass/attitude era time) completely overrated?

>has a completely played out post-kane 'master of darkness' storyline, his wrestling skills are lacking
>takes a long break for recovery
>comes back as the american badass, completely butches the Judgement Day main event finish by not interrupting the count on time
>has 0 charisma as a badass honestly, his phrases are like what a good guy pretending to be bad would say
>has the shittiest match ever against kurt angle, is still sluggish af in the ring and overall not impressive at all

Does the undertaker get better later, or were his early years the peak and he's just been cruising on his reputation since? I'm watching every match, starting from 98' onwards (at 2000 now) and don't get the hype
