Well, I think that the vehement reaction to this news is just further proof that the Trek community is as fractured as the American voting public is over politics. Everyone seems to want their little niche covered, and they spit fire upon any concept that isn't precisely what they want.
But, there are a few of us who want every Trek venture to succeed. We may not like everything that the franchise puts out (I couldn't watch Voyager, for example, and have been disappointed by three movies), but we remain hopeful the next one will work, regardless of what era it's in.
My personal preference is for the NX and TOS eras, but I don't mind going forward. I don't think I want a Trek movie/series in the mid-25th Century or beyond, but I'll give it a chance if they decide to make one.
The point is, let's avoid any hasty judgements on the movie until we've actually seen it. This is the only Trek we have for the time being, and if Abrams wants to reboot the franchise with the original cast of characters, then let's give him the support to do so. At least we can rejoice in the fact that B&B aren't involved.
