Some really bizarre movies opening this weekend in theaters. If you want some spooky supernatural entertainment you might want to see Paranormal Activity 4. Or maybe a psychotic drama thriller starring Tyler Perry in a role completely different from his Medea character in Alex Cross. And finally a drama about a man afflicted with polio "The Sessions." My choice this weekend "Alex Cross."

'Paranormal Activity 4' continues the legacy of the first three found-footage horror thrillers with a brand-new family in a brand-new house with a very familiar entity invading their lives.

In 'Alex Cross,' Tyler Perry stars as a detective out to capture the psychotic man responsible for murdering a member of his family.

'The Sessions' stars John Hawkes as a man afflicted with polio and confined to an iron lung who hires a sex worker to help him experience a physical connection for the first time in his life.
