This early entry in the 'babysitter' horror film subgenre is pretty weak. All of its narrative devices either haven't aged well or are too slight to begin with, making Fright underwhelming because it lacks, well, fright. It's too drawn out and patient for its own good, lacking a diabolical unease that a film of this genre needs. Sadly, it's without many scares and never goes for the jugular even in its horror.
A bit dated and cheesy at times, but mostly a pretty decent psycho-thriller. Susan George is a little too over the top in the lead, but the rest of the cast is good, particularly Ian Bannen as the psychotic villain. Maybe not quite a classic, but a solid, well-made piece of work.
