I was concerned about substantial changes to a myth which I found so comforting over the years. There have been subtle changes since the 60's but nothing that would turn the Star Trek World upside down.
There is decent respect for what came before. True Trekkies can pick up the factoid references to the traditional story line. But, Star Trek has been liberated from the old canon and is no longer a museum piece.
The future remains hope filled. The story was fast paced and just fun to watch.
However, leaving the theater, I pondered the Barjavel paradox. Perhaps this leaves the door open for other sequels or simply proof postive of my status as a true believer.
