It's probably legit. They released an extended version of the Series Finale on the Blu-ray release as a bonus feature.Is that an actual alternate ending or a fan made one? There's an effect in there that I don't think they'd do on the show.
And I agree it was kinda weird for them to go with an ambiguous ending. Nothing wrong with it at all because it worked for me but just for this show, going with the complete happy ending makes more sense. I do wish all this talk of a movie would actually equate to something real. Levi has been talking about it during the summer
Only thing is I keep puttin it on at night and fallin asleep
Gotta watch it in the morning so i can knock out a couple episodes at a time.

If you've EVER worked at Best Buy then you know that the "Nerd Herd" is a straight rip off of our Geek Squad and they had that shyt down pat.
