What types are considered 'bad'?

I feel like some types are relatively bad and some are really good and I can't find anything online about what types are considered 'bad' so I'm asking here.

My perception is that Water, Grass, Psychic, and Colorless are inherently good types because of their support and attackers. Dragon is a good type because Dragobox exists, similarly to Lightning and Spread and Fighting and Hitmonbros. I think Dark is good, but the DCE ban leaves it in an interesting place. I've heard that Fire is bad, but it seems to have a lot of support and some rather strong attackers. Fairy is obviously bad because powercreep and Metal just lacks the support and variety of attackers to keep it relevant.
