It didn't help the sequels that Teri Polo has looked like Helen Hunt's older sister ever since 2003. Her looks peaked in 2001.
how can a movie be ruined by sequels
a movie is movie, it stands for itself
In my opinion, the sequels are the same story but with added characters. Jack doesn't trust Greg. Greg tries to make Jack Happy but ends up making mistakes. Jack and Greg come to an agreement and Greg is now in the circle of trust.
