I’m not so much focused on how they look. Its been almost TWENTY YEARS since the OG series ended, of course most of them are going to look old, although Donald Faison still looks young we all know what thats about.
Whats important to me is the writing. Bill Lawrence was the creative force behind the OG series and with him not returning as showrunner my concern is the writing and plotting. I hope they really took their time to make sure they captured the essence of what made the show special in the first place. Just like how Saladin Patterson was able to do with the King of The Hill continuation. Update the times while keeping the charm and idiosyncrasies of the characters intact is of paramount importance.
