adam sandler vehicles are never anything special , but continue to make a load of money . 
which really goes to show the sad state of cinema today . 
while good comedies like rushmore , to choose a recent example , gets limited release and doesn't make a lot of money , big daddy got a huge release and has made a lot of cash . 
it's also nothing special and doesn't deserve the money it's making . 
but i digress . 
sandler plays sonny koufax , a unemployed new yorker with a seemingly low mental age . 
his girlfriend makes a ultimatum to him : either wise up and get responsible , or she's leaving him . 
by a strange set of events , koufax ends up with julian ( played by twins cole and dylan sprouse ) a five year old kid . 
after a failed attempt to impress his girlfriend with the child , koufax decides he wants to keep the child . 
however , social worker mr brooks ( mostel ) finds out that koufax isn't the real father and wants to take julian back . 
koufax along with his new girlfriend layla ( lauren adams ) fight to keep the child . 
big daddy really isn't that good . 
many of the jokes revolve around toilet humour , and supposedly we are meant to find julian and sonny peeing against a wall to be funny . 
there's the occasional good one liner , but these are usually strangely delivered wrong and lose most of the humour . 
the film , after all these silly gags , then suddenly turns sentimental , and this is where big daddy really goes from bad to hideous . 
the court scene at the end of the film is useless and unbelievable , and not helped by the soppy overacting . 
it's a poor attempt to win over the audience . 
adam sandler basically plays the same role he has in his last few films ( except the wedding singer . ) 
joey lauren adams is much , much better , and deserves a far better film than this trash . 
steve buscemi pops up in a funny cameo , and his scenes are pretty funny . 
rob schneider is also funny as a crazy delivery man . 
the two twins who play julian are o . k , they start out rather well , but then becoming annoying and brattish halfway through and finally turn 'all american' wholesome goodness at the end of the film , where the tear juice is turned up high . 
big daddy is really nothing special , and is not even worth it for a few chuckles . 
although it is actually well put together , with nice direction , good production design and even some montages , this professionalism can't help the fact that the script and characters are trash . 
big daddy is for die hard fans of sandler , and that's about it .
