What's wrong with chocolate available in the supermarket?

I'm doing some research into the super market chocolate available in UK for a project I'm working on.

Are you fully satisfied by the chocolate you can get in the supermarket? What would make it better? What's wrong with it?

What do you think of the chocolate available from big brands, like the C word? What do you think about more premium chocolate available in the super market?

All replies helpful! If anyone is happy to talk then please send me a message & I'll reach out to you. Chocolaty thank you gifts available.
