first of all and i would like to say that i really enjoy this movie . however and that say and i can not say that it be a good movie . i go into the theatre with pretty low expectation ( something i have learn to do ) . i be glad i do and because the plot and development wasn not stellar . the joke be low grade humor . but and i be in the right mindset to enjoy them . i wasn not the only one . in fact and the entire theatre be laugh out loud . i do not hear anyone complain after the movie come to a close . i even saw one guy fall out of his chair laugh . but again and i have to warn you and grandma boy be not a top quality film . it be a funny ( albeit low brow ) movie and and if you go with the right mindset and you will really enjoy it . oh and and do not take kid to it .
