This has the potential to be really good, but unfortunately the potential of it to be an epic failure far outweighs it. I guarantee the producers and writers will do all of the following (probably in the first episode):
1. Picard will still be in command of the Enterprise, even though he's way too old to be doing that.
2. They will bring back the Borg for this show as the main villain (because these are things we know.)
3. The Borg will do something crazy and epic, like destroying Starfleet HQ along with half of all life on Earth because they will feel like anything less won't be thrilling enough for "modern audiences."
4. Michael Dorn will reprise his role as Worf, only to be further degraded into a caricature of bad one-liners and "me Klingon, me smash."
5. They will introduce the Enterprise NCC-1701-F, even though the 1701-E should still be in service after they clearly showed it being repaired at the end of Nemesis. Also, the new Enterprise will look absolutely fucking retarded.
Why is he too old to be doing that? Hell even in todays day and age we have Admirals and Generals that are in the service well into their 60s. Admiral Rickover didnt retire from service until 81 I believe. So given that theres literally no reason Picard cant still be a Captain in the future make believe world with highly advanced medical tech.
