Saw it last night. I had never watched a full episode of any Star Trek TV series, nor have I ever watched more than five minutes of any of the movies.
Still, this got great reviews and it was easily the only thing worth watching when the wife and I were out last evening, so we decided to give it a go.
I actually liked it a lot. I do know enough about the original characters to recognize some of the jokes and references (but certainly not all of them). It wasn't perfect, but it was still enjoyable, amusing, and interesting.
I'm still trying to figure out how it relates to the original Star Trek (prequel or alternate reality), but I don't think it matters much to whether you like the film as neither interpretation would be considered to be too forced or contrived.
