Unique, a first, but I'd hate to see lame copies.
Lame copies would discredit this stlye which can be very funny, but get old as well. As for this one watching Lost actually makes it really great!
Great idea here, I'd like to see more of these"Lost season musical recaps" this one was great, and did (even with its ridiculous humor) and by the end especially represent the first season very well in a satirical manner that didn't discredit the show much, so that it may be enjoyed by Lost fans. One problem though, each time I play it it lags somewhere in the middle despite the quality setting, and I miss a bunch of clips while the music plays... if I manage to pause it (which is hard during lags) it fixes itself, now myabe my computer just really sucks, but I haven't had this problem before, maybe an on screen pause or somehting else to stop lag, because it's ten times better without it. I only wish I had thought to make that first, great job!
(note in a sequel, if you have more of what was in the later part of you movie, it would be better)
