Back in 1978, Wes Craven must have found it hard to resist this first opportunity to shoot in 35mm with studio backing, but resist he should have.
Summer Of Fear (a.k.a. Stranger In Our House) demonstrates the laziest traits of its made-for-TV origins: generic California landscapes, stock footage, lethargic script and inferior acting.
Worse, given Craven's reputation, is the utter lack of either tension or horror - unless you count the haircuts. Best ignored, best forgotten.
