My ex-wife couln't watch Jeremy Brett, said he was too histrionic, over the top. I'll have to go back to that and watch it again.
But -
I do have the Boxed set of the Basil Rathbone and Nigel Bruce movies, which defined Holmes and Watson for the twentieth century.
And Henry Caville as Solo? Nobody could replace Robert Vaughn and David McCallum in those roles, but for mine, judging the movie just as a movie, I quite enjoyed it.
On the other hand the Val Kilmer Saint movie is just wrong on every level. I don't even think Kilmer enjoyed making it.
The only way to do a Saint movie is to do it period, and to do it camp or tongue in cheek. Roger Moore was good as the character but I didn't enjoy the show. Neither did Leslie Charteris.
The George Sanders Saint movies are the closest Hollywood has come.
Speaking of Roger Moore,The Persuaders which he did with Tony Curtis is a personal favorite of mine.
Good escapist entertainment that didn't take it self too seriously.
