For this revival (which not only returned the classic series to television but also four of its original episodes - "The Killer" , "The Condemned," "The System" and "The Legacy") Peter Graves again assumed command of the IM Force with a new set of equivalents for the old unit, shot in Australia and with stronger effects... but lesser scripts.
Watching the originals again, they're miniature gems particularly in the first few years; the new version just isn't as compelling, although having Casey Randall be the first IM member to actually die in the course of duty was unusual. The episode "Submarine" pretty much encapsulates the remake's inferiority; written by the show's visual effects supervisor Dale Duguid, there's an unfortunate emphasis on how the illusion required to trap the villain is done, which suffuses any suspense.
The show does, however, have more fidelity to the concept than the misguided cinema version from Cruise and DePalma, which is why this is ultimately preferable. But the original show is the one to watch.
