While Roger Moore may be my least favorite James Bond, I've always liked him as an actor and personality.
His characterization of Bond was generally too light for my tastes (although he had his moments, and both The Spy Who Loved Me and For Your Eyes Only are among my favorite Bond flicks), but I thought he was a fantastic, charming Simon Templar, and I'm a big fan of his work in 70's adventure films like ffolkes and The Wild Geese.
Hell, he also made a great – if somewhat more suave and urbane than is traditional – Sherlock Holmes, in the television movie Sherlock Holmes In New York.
He has a new autobiography, My Word Is My Bond, coming out, and I'm looking forward to reading it. If it's half as fun as Roger Moore's James Bond Diary, in which he chronicled his hiring as the new James Bond in '72 and the making of Live And Let Die, it should be a very entertaining read.
