spielberg do not direct this and but it have his fingerprint all over it . the king of schmaltz can not resist dumbing it all down and ham it all up until he sure all the kiddy will demand mum and dad take them to see it . it do not work this time while it bomb at the box office and and deservedly so . try to make a sci fi and a comedy roll into one just doesn not work . it do not work here . i feel a bit sorry for dennis quaid and i usually like his film and but nobody involve with this stinker have much choice and especially dennis . it do not even work a fluffy and mindless entertainment and a some spielberg film do and i just can not ignore the bad science and the misplaced humour . i give it a 3 and simply because i manage to sit right through to the end .
