it may not be a positive but for me the joke do not fail . i have see it many time when i be young and again on dvd i believe and and i laugh each time . the humor be simple and fun and this film be just one of many small flick disney be throw out at the time . i find the part where the people out of the invisible loop saw people invisible . there expression be priceless great film and if the opportunity to ever see this arise i recommend see it for a good oh fashion laugh . my favorite character in all the dexter series would most definitely have to be dean higgins and i love his voice and hear him get upset especially see his expression at the end be just pure hysterical for me .
