Don't get me wrong, the effects in that trailer are decent..I'd probably watch that if it were real just because it's SO BAD THAT IT'S GOOD. One of those things. Plus, I love parody. It's my favorite form of comedy.
As for the other thing, not so much. I saw the trailer for the Yogi movie before Legend of the Guardians and me and Alek were just sitting there like WAT IS THIS MADNESS
And it's funny because right before (or after, I forget) that one was a trailer for THE SMURFS MOVIE.
Seriously...I think they are trying to see how many Hanna Barbera cartoons they can make into crappy live action movies for before this decade ends. BECAUSE THERE ARE MORE PLANNED. :C
