Even something like an iPod will support ogg files with the right firmware. For example, I put rockbox on my iPod and now it can play ogg, FLAC, and whatever other files I've thrown at it. I don't even have to use iTunes to add music to the player; I can just copy the music files to the iPod's hard drive. Rockbox recognizes them and sorts them by their tags. I didn't even have to format the iPod's hard drive. It just installed alongside the original firmware, allowing me to use whichever one I wished. Rockbox also supports a bunch of other players from Archos, Cowon, iriver, Olympus, SanDisk, and Toshiba.

Whoever made this video was either unconcerned with its aesthetic appeal or was too incompetent to achieve the desired look. The key job alone is absolutely terrible. Even on YouTube's low resolution, the soft and flickering edges of the people's faces were very distracting.
They didn't even accomplish a proper fade out! If you watch the last half second of the video, you actually see completely through the man holding the laptop.
What puzzles me the most is why they thought it was necessary to superimpose them in a perfectly normal looking room.

In my opinion, the only part of the voiceover that was unnecessary was the beginning. This is because the character who's supposed to be listening to the narration should already know what he's being told. Therefore, the opening narration seems to be more of a crutch for the audience than a believable element of the story. (However, it does introduce some important themes, such as, "They took from their surroundings what was needed and made of it something more.")

Besides the very opening scene, however, I think the narration does more to enhance the film than to degrade it. It's not like it spoon feeds every conceivable answer one might have about what happened. Instead, I think that it actually raises more questions than it answers. (Especially because it's unclear how reliable the narrator is.)
