I still can appreciate some of the episodes, but, and to no one's surprise, it's mostly the Sci Fi era, which was downright cruel at times.
Space Mutiny, Terror From the Year 5000, I Was A Teenage Werewolf, Overdrawn at the Memory Bank, Prince of Space, Time Chasers and Invasion of the Neptune Men are still very watchable, and that's because of the edge they had. Mike Nelson had a man streak with his humour, would downright berate an actors whole humanity and lack of talent, and didn't hold back at all. I admired that and most of it is still pretty funny.
It's Joel's years that have aged the worst, and he's primarily why the new years have been awful, his involvement. Joel's rule was to never really make fun of the people, just the movie itself - so the jokes don't hold up. Minus a few episodes where he let loose - the two best being Manos and Mitchell - Joel threw nothing but softballs, and by proxy, his co-hosts would too.
It's still mindless disposable entertainment, but my local television station growing up would air awful cheap films all the time, so taking the piss out of them amused me.
