I think I would go less with "legend" and more with "notorious twat". Can't stand that aggressive style of interviewing myself, especially because now every half-wit newsreader thinks they're the next Paxman by interrupting the interviewee every 5 seconds.
Paxman can be quite aggressive, and I would say justifiably, with politicians trying to avoid answering a question. For another side of Paxman see this interview with Christopher Hitchens - http://www.bbc.co.uk/programmes/p00r2c42
In what way was he being a twat in that interview? The MP kept responding to his question as if he hadn't heard it, so Paxman repeated it, many times, even apologizing for repeating it, and eventually giving up.
