I only recently saw the Steve McQueen version of this movie, having seen the Pierce Brosnan one many times. I like them both, but the old one is definitely superior and just oozes style in a way that the later one doesn't.
While I generally wish Hollywood would make new things, there's enough substance in this story that I think this could be a very cool remake.
(I have not seen them but) I feel Pierce Brosnan was born at the wrong time. So much of the cinema in the 90s was so campy. Just comparing 90s Bond to modern Bond, there’s a big difference in tone. Then again, maybe it’s actually his preference; he did do Mamma Mia after all. I can just imagine him as a more serious actor and would love to see it. How does the Thomas Crowne Affair rank in that way?
It definitely is not (as) campy as his Bond films. But I would say it has a certain "90s-ness" to it, and realism / believability suffers because of it. But overall, a good film and very worthy of a watch.
