Stay Tuned with John Ritter, Pam Dawber, Jeffrey Jones, Eugene Levy and the super-hot Heather McComb, was an excellent actors' workshop. Maybe making the time-passages seem real would've made it 'scary' or something, but making them as they ended-up (five hours to figure out how to move a a room-built-on-ice?) just made the writers seem inadequate.
It's not so unbelievable as to fit into Mystery Science Theater 3000 (as I said it was on some social site before I realized what "MST3K" stood for), and it is not targeted at kids (who would probably like most of it, save one reference to John Ritter's role in Three's Company ... which the writers could have cheesily retitled [but didn't] "Three Sixes Company," to fit with their other cheesy retitles: "Dwayne's Underworld," "Silencer of the Lambs," "Three Men and Rosemary's Baby," "Driving Over Miss Daisy," etc.)
But Warner Brothers and Morgan Creek probably only gave James G. Robinson enough money to shoot as much as he did. If they were decent film-companies, they would have given James G. Robinson an ongoing blank-check; but I guess James G. Robinson hadn't "earned their trust" ... Warner Brothers and Morgan Creek probably looked at the script or -idea, said, "Okay, James G. Robinson, we'll give you x-thousand dollars," and James G. Robinson probably ran out before marketing-expenses could begin---let alone before he could add any 'realistic time-passing'-footage.
But, if you've got a dozen extra bucks and/or some empty time to fill, Stay Tuned won't leave you too brain-dead.
