I liked the trailer because is just a trailer, for those who want more plot/substance I suggest waiting for the movie premier. Also I'm sure that there will be one or two more trailers so hold your horses.

Someone said a few pages back that we shouldn't expect a massive breakthrough since that ended on ESB (for several reasons, I think) and I agree, a good honest homage to the OT (taking in consideration that these are very different times) with a tight script will work.

Also:
-NO Lucas involved
-A lot of the original cast.
-So far there is no impression of any ''Misa misa I'm so stupid I put my tongue in a podracer electric field'' moments or characters.
-Screenplay by Lawrence Kasdan
-JJ at least tries to make decent and coherent films.
-The PT sets the bar so low that we can almost assume that TFA is not among the 3 worst movies on the franchise.

For me the worst case scenario will be a ROTJ feeling which is not bad at all.

I'm all into the hype train since this is the first SW movie in 11 years and at this point we don't know if it will suck and we hope it doesn't, if it ends up sucking then I will hate it for the rest of my life but in the meantime... WHOOPEEE A NEW STAR WARS FILM!
