Spielberg didn't direct this, but it has his fingerprints all over it. The king of schmaltz can't resist dumbing it all down and hamming it all up until he's sure all the kiddies will demand mum and dad take them to see it.
It didn't work this time; it bombed at the box office, and deservedly so. Trying to make a Sci-Fi and a comedy rolled into one just doesn't work. It didn't work here.
I feel a bit sorry for Dennis Quaid, I usually like his films, but nobody involved with this stinker had much choice, especially Dennis.
It didn't even work as fluffy, mindless entertainment, as some Spielberg films do, I just can't ignore the bad science and the misplaced humour.
I gave it a 3, simply because I managed to sit right through to the end.
