I think Adele and a few others benefitted greatly from Amy Winehouse's popularity. Amy was retro but fresh and immensely talented. So we got a host of quirky young British women with voices from the past trying to emulate what she had done.
I really, really liked Chasing Pavements - the song, the video, the voice; everything. Everything since then, however, seems to have been just a repeat of same.
Also, she REALLY needs to get over whatever break up it was that seems to constitute the lyrical structure of pretty much everything she creates. Taylor Swift gets a lot of criticism for only writing about ex's, break-ups etc. How is Adele different?
Of course, Adele has more talent in her little finger, for me, than the Swift girl has in her entire body; but neither really float my boat.
