Sure. Just as I have the right not to like pistachio ice cream (though my opinion is more meaningful, if only to myself, if I've actually tasted pistachio ice cream--same applies to the latest Trek movie, incidentally). I even have the right to complain about pistachio ice cream. What I don't have the right to do is suggest that those who like pistachio ice cream are not really lovers of ice cream or that that particular flavour is not real ice cream. I also have no right to expect that anything but pistachio will be made in the future, when it comes down to it (even if I would be highly disappointed if that were the case).
No one is forcing anyone who doesn't like the flavour of Trek served up by Abrams to watch it. It really is that simple. No one is "owed" any particular type of entertainment from any creator of such. You are simply free to choose whether or not it is to your liking.
I don't think I was suggesting that people who like the new Star Trek are not really lovers of Star Trek. I don't think that at all. I guess pretty much what I'm saying is that I don't like pistachio ice cream. Other people can if they want, but I don't understand how they could.
