What a funny little story. Gets total props for originality in my book. It's like Inspector Cluseau or Barney Fife meets the Ghost Whisperer. Martin is a retiree with a haunting problem, and he is bound and determined to deal with it...as long as his girlfriend - the living and breathing one, anyway - doesn't have him committed first.
I found the story to be more of a comedy, although there were a couple eerie scenes, and even some touching scenes. Martin's bumbling efforts to conceal his "it's complicated" status from his neighbor (who he just so happens to believe is the love of his life) are enjoyably comical. I got the greatest visual of the man going about his days, dealing with some truly trying ghosts.
Not sure how you would categorize Curses. Maybe a cozy horror mystery? It was a definite fun break, for Halloween or any time.
