Chappie Trailer

Before the trailer, I was excited to see Chappie, because if I recall correctly, it was decribed as an action-thriller. It starred Hugh Jackman, who is always great, and Dev Patel, who isn't in enough films, but has the potential to b great. Then, I watch the trailer and find out its about a stupid robot, and is this a remake of Walle and Earth to Echo combined. I am adding a new element to my trailer reviews, I will put predictions of what ratings the movie will get based on that trailer for EW, imdb, and RT.
Predictions (Based on what I've seen so far):
EW: C
RT: 51
IMDB: 6.5

Trailer Rating: C-
