The whole Futurama series was leading up to thid very moment where Fry's destiny would be explained. This episode is very revealing and funny such as the questions that Fry asks:
"What really killed the dinosaurs?"
The whole plot was very creative and if Futurama had not been cancelled, I'm sure that they would do an episode explaining the "other" which is apparently Leela. This is another teaser ending which makes viewers believe that Leela and Fry do start dating but they are still friends in the next episode.
This episode has been hinted right back in the first episode with Nibbler's shadow and is obviously a very thought out plot. Overall, this episode is definitely a 10.
