If for nothing else, then you should watch this because this is "the movie where the guy is pregnant", but I'm not sure we need a reboot: one is probably enough.
It helps that this is a good movie with a great cast. I felt bad they made Danny Devito run so much, but Arnold is great as a pregnant man, and sometimes a woman, and Emma Thompson does a wonderful absent-minded professor.
It's a unique premise, it's a good premise, and for a comedy without lasers, aliens, or explosions, there is a lot of excitement.
