User blog comment:LEGOfan2010/The LEGO Movie debut trailer is out!/@comment-3444778-20130619145551/@comment-4272842-20130620105712

Comedies are allowed a lack of plot, plus this does have a plot, if you'd actually watched it for the first minute. It's quite obvious that some parts ARE stop-motion. I am very intereated in this. It seems like a great movie, clearly they've put A LOT of work into this and it's people like you who are probably hurting them by throwing aside 4 and a half years of their work. ...You haven't been paying any attention to anything LEGO-related at all in the past decade, have you? It's almost all kid-targeted stuff these days. That's usually annoying, but in this case I don't care. And how is LEGO targeting their normal audience a problem? That's just stupid.
 * 1) Lack of any coherent plot. I know this is only a trailer, but it should at least hint at some kind of plot within the movie.
 * 1) Terrible CGI. As NW already pointed out below, it looks like stop-motion. I hope this is the result of its current progress in development, but for them to put a trailer out for it, I'm rather doubtful.
 * 1) Mass-appeal. I know this is no hard and fast rule to go by, but normally movies that 1) are filled with stars and 2) play hit pop music in the trailers fail miserably, because 1) the stars are the only thing that the movie has to boast about and 2) they need some kind of way to keep people interested.
 * 1) Target audience. I see genre-slashing, lack of any real seriousness, and head-over-heels crushes; this could only be a... yup, a little kids' action-comedy movie. And I can just about guarantee you that the funniest lines in the whole movie were used in the trailer there.
