This is an updated "Fantastic Voyage" and interestingly done, I thought. Joe Dante directed a number of fun movies to watch.

It's not the innocent Steven Spielberg "E.T."-like movie I expected because of the language and several sex jokes. In other words, this is not a kids' movie.

Dennis Quaid stars and plays his usual cocky self. (He's mellowed in recent years.) Meg Ryan is her usual cute-but-of-little-substance self and Martin Short is just plain funny - the best guy in the movie.

The film offers a good combination of humor and science-fiction suspense. It's a fun movie I would rate higher if it weren't so silly in spots.
