No they were not, movies unfortunately cannot be like the series. People need to understand that. The movie will not succeed or fail due the Constitution class size or shape but due to viewership numbers.
In that respect JJ has been sly. He has added humour, [i cant wait to see Kirk's gags as given in the reports] he has added flash and effects for the action junkies [me included]and he has hopefully added some real sentimental stuff for laying the base for the franchise to begin anew.
