"Psycho" is on this recommendations list for two reasons. The first is that it fits into the domestic thriller genre. In this case, it's about someone entering a monster's home, upsetting the balance, and the monster retaliating to protect itself. Second, there's a massive twist (that everyone probably already knows) that means the second half of the film is much different than the first. To elaborate, a few things need to be spoiled. So, if you've never seen this classic, do so now and come back when you're done.
The front of "Psycho" is about a woman named Marion Crane (portrayed by Janet Leigh) committing a crime (stealing from the bank she works at) to achieve the life she's always dreamed of. While fleeing, she's forced to stay at a small roadside motel. The proprietor of the location is a nice (if quirky) young man named Norman (Anthony Perkins). Little does Marion know that Norman's relationship with his mother is going to prevent her from leaving the motel alive.
Released in 1960, this Alfred Hitchcock masterpiece hasn't aged well in certain respects. Its depictions of Norman's mental disorder are problematic in a number of ways and should be called out as such. If you're willing to acknowledge those faults and still give them a chance, you will not be disappointed. Other than the unfortunate nature of the final reveal, the filmmaking artistry at work here is simply exceptional.
