Here's a classic case of bad music spoiling a movie. There is way too much of it and it is way too loud. I often found the need to mute the soundtrack and follow along with closed captions to spare myself the misery of the insipid score. Music should be enhancing, not overwhelming. In addition, I have to agree with other reviewers that some of the butterflies seemed to be the product of CGI, which was also disconcerting, as was the overall gearing of the film toward a school-aged audience. Nevertheless, the inspiring story of the Monarch migration and fortuitous convocation of events that resulted in its eventual discovery make this film worth viewing. But you might want to keep a finger close to the mute button.

I saw Flight of the Butterflies at the IMAX theater of the American Museum of Natural History. This was one of the most interesting short films I ever saw in an IMAX theater. Usually the films take advantage of the format, even abuse it, without much story. This film has an excellent story line. The IMAX format allows the viewer to immerse into the presented world, but you never feel they made this for the sake of showing off the IMAX. I learned about the butterflies in these 45 minutes more, than in my entire life. I came to admire and appreciate them. Without giving too much away and any spoilers, I can tell you it follows an individual specimen through a complete cycle for a year. You will be amazed. I would recommend it to anyone age 3 to adult.

I was looking forward to seeing this film, both for the IMAX 3D format, and for the Monarch butterflies which are in news recently for declining population.

Cons first: This film doesn't really make much use of the 3D format. Those things which have the most 3D effect appear to be CGI, rather than actual butterflies. I don't know whether they are, but the fact they look like they might be is disappointing. Peter Jackson is right when he switched to High Frame Rate for 3D, to reduce motion blur or snapshot effect, and look more life-like. Also, the IMAX at the Henry Ford Museum seems to have some trouble holding 3D together. Sometimes there's 3D, and sometimes (particularly toward the edges of the screen) there's just two flat 2D images next to each other. I attribute that to the theatre, rather than the film. But viewers should be aware that it can happen.

Pros: This is more on the monarchs than I've seen before. But it's presented at a level that kids can understand. And it does seem to do a good job of covering the story of the discovery of the migration route between places like Toronto, ON, and a forest in Mexico. Actors portray Urquhart and his wife, and two other in Mexico (Wikipedia says Brugger and Aguado, but I'm unsure if that's who they identified in the film). It is thrilling when the migration route is discovered, even though we all know it's coming.

I'd recommend the film, but probably not in 3D, and maybe not in IMAX either. The content doesn't justify extra expense.
