With Stuart Baird's direction (even though many would say he's a much better editor than a director), and John Logan's (Gladiator) pen, they thought in far more epic and wide screen terms. The action fills the 2.35:1 aspect ratio much more capably than Gen, FC, and Ins. They take full advantage of the widescreen aspect.
I'm of the opinion that Baird didn't get enough credit or chance as a director, yes there were problems with Nemesis, with some people falling out etc, but I still found the end product much more polished than the previous two. Nemesis's problems lie in the script/screenplay, not the direction.
I thought U.S. Marshals was a solid, well paced but ultimately unremarkable film that suffered probably because it was a sequel to a very successful and well liked movie. In it's own right it was a decent action thriller.
Executive Decision on the other hand is one of my favourite action movies of all time, and an extremely tense, yet preposterous adventure that had the balls to kill off Steven Seagal quite early in the film.
So I don't believe his record as a director stinks anything like people would have you believe, I think if Nemesis hadn't bombed in the way it had he would have directed more movies.
