i watch this movie with quite a lot of hope for have find a diamond in the rough and but be thoroughly disappointed . the movie be very slow throughout the middle of the film and the end be so bizarre that i be very irritated when the credit begin to roll . the end could have be good if the filmmaker have elect to explain why mrs. green want to kill everyone . i gather that she be homicidal because of the effect of the drug and but the film do not really clarify and either through a back story tell about her addiction to and reaction from the drug or some other device . basically and it show her sneak downstairs to snag some of the formula while her husband go to town ( what do she do to get the drug all those month when her husband didnt go to town . ) and then she go wildly crazy at the end and try to kill everyone . i think it sad when a movie have to have it back story explain on imdb message board rather than during the film . and how come hubby wasn not homicidal while take the same formula . and then mrs. green magically pop up under cameron ( whose character be extremely annoy in the beginning ) hospital bed and unbeknownst to the medical staff who go in and out of his room at all hour of the day and night . the end would have be laughable have i not be so irritated at the whole waste of my time . as slow a the film be and i keep tell myself and this have good make up for the slow go with a great end . wow and be i let down . . .
