@2a70c54d That seems like it would be worse.  As in "there is no longer a movie starring Sinbad as a genie named 'Shazam'; it never existed" worse.  Granted, I never saw it when it did exist because it sounded like it would be a waste of $4, but still, if aliens weren't ramming dimensions together to make their alien drugs, I wouldn't even have to remember the idea of it. 

 @e0c85d7a have you ever read the Doors  of Eden? Lol, strikingly similar to what you've described
