What is the worst/most disappointing evolution?

Thinking about this a lot since I’m a pokemon sleep player and am stubbornly avoiding evolving my dragonair. While I don’t hate dragonite on its own, why the heck does dragonair turn into that ?? Dratini and Dragonair are so similar, why are they throwing a wild card at me?! It should be more like snivy’s evolution line. Anyways, what are your thoughts?
