I was a serious hard rock/blues rock fan in the early 70s so I really looked down on all the glam-rock bands passing through Top Of The Pops as not being worth much musically. Slade however were fun and had great singalong songs, same with Mud . I only liked Sweet's Ballroom Blitz at the time. TRex came across as too airy-fairy (but I now like a lot of Bolan's work). I thought The New York Dolls looked like a poor Stones parody when they appeared on The Old Grey Whistle Test but I really got into their two albums once punk kicked in (I finally got it). Bowie was the exception. Through the glam it was obvious that he was a true great (and he had Rono on guitar!).
