I did this before star trek XI. After i saw the 1st trailer for the movie, i had the urge to rewatch it all. I watched as much as i could, but it still took me about 2 years to get through it, and it was totally awesome. I did go the ENT, TOS, TNG, DS9, VOY route. It was pretty fun, but if youre new to Trek, id def start with TOS.
