Involuntarily I have watched this one on TV. It was good, had an okay storyline (even though pretty unrealistic... but that applies to all movies of this kind), and most importantly it didn't have exaggerated cheap and lame humour a lá Police Academy or similar. This one might even entertain grown ups. I'd say this movie was one of the better kid's flicks (not saying that Police Academy is one, but honestly, it's a big piece of crap). However I can't judge the original version since I've seen the German dubbed version which was pretty ok. I think it's underrated here at IMdB. I give it a kids/comedy rating of 7/10 (please note that this is not a generic movie rating. imo you cannot judge all kinds of movies the same).
