It's incredible how some of these things get made. A few sad, decent comedy actors taking on some awful scripts, unrealistic 70's clothes, and making it look like 70's USA for gods sake. I'm aware of its provenance, but I really would advise against making copies of shows which were already 10th rate before they sold the rights to some unsuspecting Brit tv company.
Dubious stereotypes and sloppy sets make up 30 minutes of the incredibly dumb show. Ironically, it's ACTUALLY entertaining for completely the wrong reasons. It's a classic case of "traffic accident syndrome" - you just can't HELP watching.... you think it's going to get better... but it doesn't!
Oh, by the way, message to the previous reviewer: don't go making personal remarks about actors' looks, mate, it's just plain rude. The idea is to crit the show, not the biology.
