I wouldn't really call U.S. Marshals a sequel, per se. It's more a film that takes place in the same universe as The Fugitive and features many of the same characters.
Maybe a spin-off would be the right term.
In the genre of the 30-years-later follow-up, I actually wouldn't mind another spin-off from The Fugitive ... if it followed the same format, and was as tightly written as the original.
