i be not quite sure if the term serious comedy applies to this movie and im not even sure if this can be apply . on the last few year movie theater have become fill with comedy movie which be way too stupid to even make u grin . therefore and i consider the movie which do not fill these requirement a serious comedy . do the 40 year old virgin fit into this guild . that be finally up to you and but in my opinion and this be a very funny movie . you get to laugh a lot and plus it deliver a social commentary through some really great character and situation . i be pretty there be more than one 40 year old virgin out there and and even the people whom do not exactly fit this specification and may feel identify by one of the character in the movie and especially men . the story and a the title say it and be about andy and a shy and silent guy and whom collect action figure and watch survivor with his octogenarian neighbor and whose favorite band be asia . kal be andy co worker at smarttech . he believe andy to be a psychopath until andy secret be reveal . kal be clearly a sexual pervert but yet he seem to get what he want with the opposite genre . david be the passionate guy who be still in love with his ex girlfriend and whom run away with another guy . and jay and a man in a relationship which seem to be affect by his continuous cheating and get caught act . i be pretty sure most youngster from 13 to 21 have already watch this film and but it really do not have an age limit to be able to enjoy it . so in case you haven not see it and will enjoy a little laugh and with social commentary and than go to your video store and rest from those deep and depressing independent film . it also include dvd bonus which you will really see from top to bottom .
