I love her music, but I hated the staging of the music video; why did the director restrict Adele to a chair? Other people play drums, twirl, dance but she is compelled to perform sitting down. I suspect that it was Adele's lack of a willowy figure that figured in the director's choice.
For counter-balance, here is the same song in a performance recorded live before an audience. For purists, an accoustic version can be found here.
For the record, this is what Adele had to say about critics associating her music in with Amy Winehouse and Duffy:
"We got lumped in together, but I don't think we sound alike at all. We were trying to achieve the same things but we're a gender, not a genre."
