I really dont understand people sometimes tbh...
I consider myself a pretty big star wars fan, and I personally am incredibly excited to see this show and hope that it eventually gets made. If you're a Star Wars fan, then there is some enjoyment to be had from the show being that its 'Star Wars'. And if it ends up being terrible (as most people are assuming is likely)... so what? Does it make the movies any worse? Does it suddenly remove the original trilogy from existance or something?
If you dont enjoy it thats fine, you dont have to, even if you are a fan of the IP. But that doesnt mean that others wont enjoy it. There would undoubtedly be millions of people who would love to see it, yet you all cry and scream and hope that this show never gets made so that you dont have to see it? How about simply not watching it?
And furthmore what if by some incredibly slim chance it actually ends up being amazing - Isnt that worth the risk? (inb4 "no").
There are 2 outcomes:
1. its awful and you dont watch it - nothing gained, nothing lost.
2. its amazing and you watch it and love it - huge gains, nothing lost.
Whether you like it or not, this show WILL get made eventually. You dont write 50 hours (2-4 standard tv seasons depending on length) of material if you dont plan on doing something about it. Better off coming to terms with it rather than complaining about it which wont do anything. When it finally does come out THEN watch it and decide for yourself - or dont watch it, the choice is yours. I personally will watch and hopefully love every second of it.
