This is a quality thriller, it has an almost vintage feel about it, it's a straight up story of a woman being stalked by a sinister being.

It's not a complex story, but Julia's conflict is what's interesting, is she simply paranoid, is she unfairly maligning the guy living opposite?

I loved the ending, that was such a good, dramatic scene. I know what I'd have said to Francis.

Maika Monroe is excellent as Julia, you truly get the sense of the character's loneliness and total frustration.

Burn Gorman is very good as The Watcher, he plays these creepy, sinister parts so well.

This film held my attention from start to finish.
