I find the younger you were when you saw something the more likely it is that you will find that what was “great” really blows chunks now. Another warning sign is if you remember it for some reason other than it being funny. Our sense of humour changes as we get older, but I guess not as much as out tastes in special effects, or grand intellectual ideas.

And of course, sometimes, when we are kids, we can just look past the cheesy styrofoam sets and pathetic dialog easier than when we are adults.

It’s before Oblivion’s time, but Kelly might remember “Starlost” or “Earth Ship Ark”

It had some great ideas – the initial concept was developed by Harlan Ellison – and as an 8-9 year old I loved it. Now, even though it still has great ideas it is just too painful to watch the cheesy special effects, the cheap sets and the horrible acting and writing.
