Great fun...
This was a funny way of representing Lost lol.
You forgot to mention Terry Pratchet for the use of the Great A'tuin from the Discworld novels, and Monty Python for the Great big foot (Can anybody remember whch one that was?).
All the classic scenes and the most funniest music very good.
Did you use the actual Program for reference when you did the painting style?
Things to change: add credit Terry Pratchet and Monty Python for their respective ideas in the movie.
Else fine.
