I enjoyed the episode. I can't see why anyone would fear that Phase II, JJ, and Continues would produce 'too much' and we'd get sick of it. Most TV shows produce over 20 episodes a year. I don't know how many Continues will produce, but I'm betting it will be less than 4. Phase II always wants to produce more, but they seem to produce one a year. JJ produces one every 4 years. Plenty of time for writers to come up with something new and original... if they are so inclined.
I don't get why anyone would say or feel that way either. I mean, it's not like they have to watch any of these fan productions. I was happy that the cast and crew took so much effort with Continues to evoke the feel and spirit of the original series. The same can be said for New Voyages/Phase II and some of the other shows. Heck even when the production values aren't there the love of Trek is and that counts to me.
Despite the great cast, FX, and spectacle of Into Darkness, seeing Continues was a welcome respite.
