Although I liked Timothy Dalton it has aged badly, suffered from being made in the 80s - since when did Bond where a thick knitted jumper rather than a suit? But at least these films has some hardcore gritty bondness.
Pierce Brosnon is an excellent Bond, especially Golden Eye, but the more recent movies have been a bit naff.
Roger Moore added some great comedy to the series, Sean Connery was the original and perhaps starred in the best Bonds.
George Lazenby - hmmm, I guess he didn't have a chance to show what he could do, and OHMS is my worst Bond film, its the speeded up action and poor dubbing that put me off that one!!!
My fave films:
Golden Eye - nicely done
Gold Finger - best car, enemies etc
A View to A Kill - good action and good bad guy
Live and Let Die - the best Bond (boat) chase ever
Form Russia With Love - good old Bond
Moon Raker - gets the prize for being the oddest most far out of the lot
Dr No. - gets the prize for being the least Bond like (even though it was the first) - no gadgets etc, bit boring IMO
Never Say Never Again - Is an oddity, being "unofficial", the return of Moore etc, strange Q
