The movie had a fantastic storyline. But thats all it had. You keep thinking that something would happen now and keep hoping that it happens but it doesn't. And since the director had no idea how to stretch this one sentence story further. He adds some russian flies who are planning to sabotage the US mission and some US flies who are trying to stop them from doing so, which could have worked only if they had some real sense of 'oh my god' moments or even some 'wise cracks'. But that was not the case.
The reason why people go and watch animation movies is that they take you away from the real world into a world of possibilities. Where things which cannot take place do take place. A world of impossible-ism and making it possible. The ideation part was good. The characters on paper were cute as well. But the execution (and i repeat 3d was crazily kick ass) was not too great.
The director just didn't know how to take it forward. I am sure the moon mission in itself would have been pretty adventurous with a lot of ups and down in reality. Rather than exagerating those moments, the movie just makes it a too-simple a hitch ride. The flies just get in, reach the moon, wave and come back. Absolutely no adventurous. No breath taking moments. No 'oh shit they are gonna get killed' scenes. Absolutely nothing.
The only positive thing that bound me was Absolutely Stunning 3D effects. If you have seen Avatar, Clash of the Titans in 3D. Do go and watch this and THEN you shall realize how pathetic they looked in 3D if you compare with Fly me to the moon. The flies are almost at your nose especially in the first 2-3 sequences and that sets the pace for the movie. Just lack of direction and screenplay couldnot keep up with the technology or else it could have been an amazing movie after Up.
Feel-O-Meter: 4/10
Overall : Take your kids if you have promised them to show some movie this weekend or if you want to experience some REAL 3 D
PS: Just noticed that movie was released in US in Aug 2008 and was the first animation 3D movie. The Effects seem even more impressive now.
