Play Black & White!!
Like some, I don’t think Psycho should be sequeled. However, this is really a very good follow-up. And if you want to capture an authentic feel in a somewhat Hitchcock way, watch in black and white. I think you might be amazed at the visual resemblance to the original, enhancing the story even more.
Not as a plug, for those who watch on a large PC monitors, there’s a free player called VideoLAN (VLC), whereby you can remove color and tweak the brightness and contrast.
