No reboot unless it has some of the original characters in their original roles. Maybe it could be fun to have it be a retirement party for Mahoney and some of the others.
I remember them well, and thought that the first was the best but some of the others were also kind of cool. I think the one in Miami, although it was kind of forced, was OK.
One thing that I did not like was that Steve Guttenberg stopped appearing in them, because I remember seeing him interviewed after he had made it big and they were still making the movies and he said he owed his career to P.A. and would always do that series as thanks. Then all of a sudden he stopped needing to thank them.
Then again, what can you expect from a Stonecutter?
