The trailer does little to no justice to the quality of the movie itself.
The movie itself has a deep and involving plot that carries a deep message with it. The casting choices were perfect for this movie and Hiccups(the main character) voice was perfect for his personality in the movie. Toothless was amazing and in some scenes I almost couldn't tell it was CG.For the past few years Dreamworks has been very dry but this new movie seems to be just what they needed. Its from a writer who is completely new to Dreamworks, the same guy responsible for Lilo&Stitch who was fired from Disney because of some disagreement over the movie Bolt.So this movie is basically a second chance for Dreamworks, I hear they are making a sequel but lets hope they don't get carried away like they did with Shrek. Maybe, just maybe Dean DeBlois is exactly what Dreamworks needed to get out of the endless rut they were stuck in, or this could have just been a one time great movie followed by terrible sequels.

I mean, isn't that what it looks like? And I gotta agree with the other reviewer, my inner nerd loves the idea of having a pet dragon. Hagrid would be so into that!

Its fire breathing dragons. Its a kid with his own fire breathing dragon. Seriously...you cant tell me that your inner nerd (and yes you have one because your viewing the trailer.) ((but remember being a nerd is the new cool)) loves to see something like this come to the big screen. We cant have enough dragons. Im just glad its not another cuddly,big eyed cartoon style creation. Remember this isnt for grown-up scrooges. Its for kids. My 6 year old already loves it. But then hes looking at it from a point we can never go back to. But I will keep trying.

It actually doesn't look too bad. I'm a 3d artist, and on first glance the dragon's visual seems out of place. He kind of seem like an easy way to texture a less detailed dragon so that they can focus on the animation and render time. I did see another dragon in the trailer that looked more detailed and huge so maybe they wanted that one to out shine the black one with detail and texturing because it's the main boss. In other words, save the best for last. Also the boys voice doesn't fit the character. He sounds older than he looks or something and to me believable facial animation doesn't have to be so exaggerated. I still really want to see this movie because I am a 3d fan and it looks like it will have some cool flying scenes and will be funny in a lot of parts. I love 3d scenery and where there's dragons, there's beautiful detailed scenery.

Looks like a Pokemon. I think it looks cool, and if you think that dragon looks bad please by all means try and model a dragon and animate it. Not so easy

Dreamworks has really been hit or miss with their movies for years now. This is just another half-arsed attempt to create something they think will catch on so they can milk it to death. What they've ended up with is something that looks really bland and uninteresting, has a main character that will be painful to listen to for the whole movie, and a story that really doesn't seem all that interesting.
