8. Guinan
Time to give DS9 a break. I loved Next Generation and most of its characters, but there was the odd one that I could certainly have lived without. I'm glad Guinan wasn't in every episode, because if I'd had to look at her smug, supercilious and serene face one more time I just might have been looking for a new television. Her attitude of superiority, that sense that not only did she think she knew everything, but probably did, really grated on me and as for that stupid pizza hat she wore: well for that alone she should have been sucked out an airlock! Yes, Data, sorry, I know: that's blown out, not sucked out.
