I'm glad they're making "The Dark Knight Rises" in such big and bold lettering here as opposed to the tiny font that was in the TDK campaign. In TDK, audiences could look up at giant billboards and see the Joker and immediately know what film it was, but in this they need the lettering to tell them the title and--hopefully--as soon as they see "THE DARK KNIGHT" on the poster, they'll be sold.
While I don't hate the 3rd poster, I do think it would have been better had WB stuck with the same concept with the 2nd poster. Something like this:
teaser poster: same as is only without destuction (signifying peace time at start of movie)
2nd poster: teaser poster background, with destuction, maybe darker clouds, a pic of bane pushing a remote detonator and the tagline "A Storm is Coming"
3rd poster: same as what we have now
If WB had done this we would kind of have a plot synopsis through the 3 posters. Poster 1 would should peacetime, poster 2 arrival of bane, and poster 3 return of batman. I think this would have made the third poster more successful. Although if WB did use this concept we would have 3 posters using the same background, and they probably look fan-made like the 3rd poster currently does.
