Judith Light is excellent as the mother, Anna Lerner, who tackles every situation with a good sense of humor, and seems to be a very good and loving mother, who just wants the best for her sons.
Tom Irwin plays Dr. David Decker, who does everything he possibly can to help the family, and....well, I won't reveal too much of the plot, but he certainly likes them all, and is very likeable himself.
Fans of Christopher Reeve and Brad Dourif (whom I am one of) will probably be a bit disappointed because they don't have much time in this movie, but they seem very believable and act great in the short time they do get on the screen.
-I couldn't avoid laughing when Dourif was introduced by the kid's as "Kirby, the gravedigger...people say he's insane and has buried 10 people alive!!"... because he almost always plays psycho-roles like that, but this one was quite different, and not at all mentally deranged (well, maybe a little bit, but in a good way).
Chistopher Reeve is Denny Gabrial, a man in a wheelchair (of course), who becomes very good friends with the little boy in the wheelchair. It is a very sympathetic role, and it is nice to see him make a comeback to the screen again, although his role is somewhat small and not really a part of the plot.
When all adds up, this is a movie who kids may like (because it shows the relationship between two brothers, and how hard it is to cope with the fact that ones brother is disabled, and so forth). Parents will probably also like it, because it shows how hard it can be to be a single parent, having a handicapped child, etc.
Even though I mostly watch action-movies, this one was good in another way, and I give this movie 7/10, because I felt good watching it, and had a good feeling after it ended, and also because I liked the cast.
