A repeated subject though a fresh movie

Rating: Null/10 (5 September 2011)

SUPER 8:while shooting for their movie 6 school child witness a train accident after which strange things starts to happen in their town which have some connection with U.S. AIR FORCE,air force officers provide no information about the accidents but they spread a wild fire so that they can evacuate the town.though we have seen such movies many times,super 8 provides freshness,the way the secret is kept that,what is it that is causing this destruction is amazing,in final 20 minutes the secret reveals and me n my brother completely failed in guessing what is it?which is the biggest victory of the movie.super 8 doesn't entirely depend on heavy special effects,the main strength of the movie is its well written script and screenplay which reminded me of THE MIST,all the kids have delivered a v,natural performance and whole credit goes to j.j who just didn't wrote a good script but also executed it by directing it well,but i didn't understood why movie is in time period of 1979 and why is it called super 8? but indeed a good movie and worth a watch.
