I've seen this movie several times, when it comes out on DVD it'll be added to my collection.
The story is great, there's no bad language and there's just enough comic relief to keep it all light--like a good Disney movie should be. The acting is typical Disney and you see a lot of the same faces as in other Disney movies. The plot revolves around an inventor that develops a robotic dog "security system" who looks just like his real small dog. A lot of the comedy comes from watching this tiny little dog beat up the bad guys, bust through brick walls and otherwise perform amazing stunts--really well done. This is a movie for the whole family although the kids will probably cry just like I did in the one really sad part of the movie (and no, I won't blow it for you). This is another Disney classic along the lines of "The computer that wore tennis shoes" and "Flight of the Navigator." For it's time, this movie was way ahead and is also just plain good sci fi.
