I enjoyed watching Star Trek TOS although I don't consider myself a fan. It was one of the best sci fi series on TV at the time. I also enjoyed TNG but I never got into the Trek spin off series.
I thought the first movie was kinda crappy. Too little plot, too many views of the new Enterprise. I loved the second one though! Ricardo Montalban was phenomenal!
I also enjoyed the new Star Trek movie. Sure, it's different from the series. Sure, it's more action than acting. You have to remember that they are created for today's theater goers. The ones that walk around with their faces glued to their iPhones, android phones, tablets Etc.. If nothing happens in a movie for over 30 seconds, they get bored.
I don't compare these movies with the older movies or the series. I take them for what they are. A new version using the same characters. (Names and job titles at least)
I have yet to see Into Darkness. (waiting for the rush to die down) But from the clips I've seen it looks to be as entertaining as the first one.
