Him sitting there barking (hurr hurr pun), "god damnnit, god damnit, crap, furry, god damnit" does not accomplish anything. He's just sitting there swearing at people critiquing the trailer. We've already had intelligent responses to our concerns from the staff on the forums.
Another thing, the "it's a trailer" line does not work. A trailer should let someone know if something is worth watching to them. It is supposed to sell itself. If it doesn't do that, we won't buy it.
Take Disaster Movie ([link]http://www.youtube.com/watch?v=0UgCrZfjPsA[/link]) for example. From it we can tell that all the movie will sell are poor character impersonations with little actual comedy. They don't care enough about the subjects of parody to get anything more than a cheap, Halloween costume (Iron Man), they don't have a firm grasp of comedy (dropping a cow on Iron Man), and they steal jokes, and poorly rehash them (Zohan/baby foot thing). This is not a movie anyone should have to or want to see.
Similarly, this trailer shows a yippy angry chihuahua boss yelling at people to do things or they're fired, a nerd who is being verbose around a female character (who admits she is a token female and has no other personality whatsoever), and a hippy... all not doing anything. There are no jokes (maybe that last line from the hippy), we can tell it has a good cast of voice actors, but the characters are completely typical of anything we can find anywhere. The trailer doesn't make me want to watch the show.
I'm not prematurely saying this is a terrible series, and that nobody should watch this. I, myself, am still going to give the series a shot. I am merely pointing out that the trailer is unappealing. It lacks character, a sense of direction, and doesn't tell us why we should watch it. Yes, "it's a trailer," "it's a trailer," "it's a trailer." But a trailer is the only thing we have to work with, and it wasn't a very good trailer.
