What About Bob was a really good one, but is really underrated in my opinion. The story was spot on, but the humor got flat from time to time. It was good, though, had slight problems, but a good comedy.
What About Bob follows Bob Wiley, a neurotic man with problems that he needs his therapist, Dr. Leo Marvin, to fix all the time. It seems as if Bob can't live without Marvin when he literally travels to his summer home and lives with him, driving him nuts to the point where he plots to kill Bob (yup, spoilers were unleashed)
Great comedy, hilarious scenes. Not much wrong with this, just a few jokes were flat. Great one that's very underrated, check it out if you have a chance.
