I liked this movie when it came out, but I was a pre-teen. Now, it's fair. No classic and no extreme adventure; and definitely very unrealistic with kid jokes to make matters worse. However, it does have it's exciting parts that keep you on the edge of your seat. A few times it really does get you going. I wouldn't recommend see it without kids around, and would only see it if there really is nothing better to see. However, it is better than a lot of family movies, and is worth a try if you're willing to lower your standards.
All the more, and on the plus side; it really has a good plot and good moments. If you really give it a fair chance and "read between the lines," there are hidden messages about team work and self-development. The man on the run has a good heart, but is facing lots of problems. People (even the kids and witnesses) like Arnold's character better than the Dad. The Dad, selfish in the beginning, really learns a lot about putting others before himself - while making a new friend and bettering himself. The kids, who argue in the beginning, also form a bond, and have some good learning moments. They all work together as a team, and it leads to a surprise ending.
No classic, and probably only a 5/10, with just a C grade; but that's better than rock-bottom, and is an all-around adequate movie worth one watch if there truly is nothing better on TV or anything better to do.
