Sometimes trailers are deceptive and only paint a picture of the movie's lowest common denominator viewing public, but sometimes they're dead on about the tone and humor of a movie.
Cloudy 2 seems to be just a bunch of running away from sentient food while they telegraph their humor lazily. It looks okay visually, but frankly, I would rather watch Planes, and I have no-ho-hoooo intention of seeing Planes.
As for the first one, maybe it was that third part that I saw, but I was mortified by it. I still don't see why everyone is so gaga over that film. Maybe they never read the book and didn't get offended by the movie thoroughly doing something I can't say here to the source material (seriously... it's my favorite stand alone kid's book)... And yes, I know there are times where they totally disreguard the source material and we get something good out of it, like Disney's Jungle Book and Roger Rabbit... Gary Wolf liked that version so much better than his own, his follow up Roger Rabbit novel was a sequel to the movie and saying that the first book was a dream.
But I don't see how sweet tall tale told by a grandpa to his little grandchildren isn't completely better than well meaning scientist with father issues.
