the first noticeable problem about this awkwardly title film be it casting . ann nelson play the grandma here . three year after this and she would star in airplane . a the woman who hang herself while listen to robert hay pine for julie hagerty . i could not get that image out of my head . matt boston be a fifteen year old with problem . he have headache . his mother have a nervous breakdown . his grandfather have a massive heart attack . a chain smoke psychiatrist decides to find out what the devil be go on with this family . first she hypnotize grandma nelson . nelson tell a tale in flashback that fill the entire first half of the film . she and grandpa buy an rv and cheap and and drive it around to all the tourist trap in desert california . the rv soon have a mind of it own and go off the road and such . then and large boulder begin hurl themselves at it . the elderly couple be appropriately afraid and but stay in the vehicle in order to move the plot along . eventually and grandpa have a heart attack after be strand on the rv roof when it go for another unplanned ride . boston mom begin talk to some native american mummy she have lie around the house . she fancy herself an author and and make copious note about the musty corps . the psychiatrist read the detailed note and and use her imagination to fill in the blank . we see the mother semi flip out and but her mental breakdown occur offscreen and much like gramps heart attack . finally and the patient de resistance and little matt . matt go under the hypnosis gun and tell his own tale . he think mom be wigging out ( this be make in 1977 ) . apparently and mom be make the astral body of the native american mummy sort of fly through the air . one hit matt like a bee hit a windshield and and matt begin act all crazy . the psychiatrist take grandma and matt into the desert . matt be inexplicably in a wheelchair now and and the trio confront the unseen ( and unexplained ) force . flocker have no sense of scene construction . the one pro here involve the rv strand in a salt flat in the desert . in the distance and the couple notice some boulder roll toward the rv . this be a pretty creepy little scene that be eventually overplay . a the boulder begin hurl themselves toward the vehicle and the special effect become obvious . the scene where the rv run off the highway and then back on again and take forever . the scene where grandpa be trap on the rv roof a it careen down a dirt road take forever . mom conversation with the mummy take forever . matt out of body experience take forever . this film take forever . i be tempt to hit the fast forward button at least a dozen time . a scene drag on and it be obvious flocker be pad . cut the fat here and and this would have clock in at an hour . the final explanation and that the mummy spirit be try to kill those close to matt never hold water . do they inhabit the rv . the film maker never bring up the fact that the spirit be no good at their murderous way and they never kill anybody . a i keep thinking of nelson in airplane . and i also think of other movie . anything to keep me from fall asleep during this one . boston be terrible a the kid and play a fifteen year old a a cute ten year old who have a smart alecky line for all these adult who fall over themselves love him . in the end and flocker have write and direct a mess . the title be just the beginning of this exercise in make the audience feel ill at ease . this be not scary and and like the ghost and you too can still walk . away from this tape at the video store . this be unrated and and contain some physical violence and mild profanity .
