The Pursuit Of Happyness. A bloody miserable film.
Funny People. Wrist-slashingly depressing.
Joy. Dispiriting.
And one that isn't necessarily over-hyped by the title, but certainly by the publicity...Slumdog Millionaire. Billed as the "feel-good movie of the year", it featured a heartwarming scene of a child in poverty having his eyes gouged/burned out.
