I thought they did a decent job bringing back the series with Eccleston but the show got awful with Capaldi (who is a great actor and would have been the perfect Doctor with better writing ). They tried gimmick casting since than with lady Doctor and gay black Doctor
The problem is the writing and it’s probably time to put the show on hiatus for another couple of decades
Capaldi should have been a perfect Doctor, but like you said, the writing let him down. After Clara left, it became unwatchable.
