I can't say I saw these in theaters exactly. . . some of these were made a few years before I was born but were still big during my childhood in the 80s, some were TV movies. Some I just didn't see till they were on VHS. Anyway, here's a bunch of awful stuff that I used to watch as a child:

The Boy Who Could Fly
Not Quite Human
Pete's Dragon
Return To Oz
Flight Of The Navigator
The Cat From Outerspace
Adventures In Babysitting
Gotcha
Condorman
Doctor Detroit
Innerspace
The Last Starfighter
Little Monsters
My Best Friend Is A Vampire
