I don't mind this franchise borrowing a teaser style from another. At least it's another franchise I [mostly] like. It could be much worse, imagine if they were borrowing teaser ideas from Twilight
Personally, I didn't think TDKR
was all that great but hey, if the average movie-goers liked it and seeing this teaser makes them stop and take a closer look at what it is promoting then it achieved its intended purpose.
