I think I will have to see the movie first before I can sufficiently describe how I will feel if it is a total reboot.
In general, I have no problem whatsoever with the direction Abrams is taking this movie. I am willing to give him, Orci and Kurtzman a chance to "do their thing".
I also look forward to seeing how this group of actors portrays the characters.
Characters from various genres are portrayed by different people in different ways all the time. As much as I sometimes dislike change, sometimes change isn't always bad. So, we will see how this all turns out...whatever they are calling it these days (i.e. reboot, re-imaging, quazi-something or another).
