All of Dave Filoni’s shows are decent but overrated at best (ATLA/TCW) but mostly kinda bad. The Mandalorian is his best show, but it seems that it was good in spite of him. The two episodes he directed were the worst two.
You did NOT just say ATLA is overrated.
(TCW might be a little overrated though. I think it’s great and I love it but it irritates me that so many fans just cherry pick the good parts and ignore the bad)
Also, Filoni only touched Season One of ATLA. That’s easily it’s weakest season.
