even if its an unpopular opinion: slime season 3. It’s a transition season with a lot of meeting and not a lot of action but it’s ok because they are preparing for season 4 and the meetings are pleasant to watch.

The first season alone is meh, but the second season twist completly the 1st season feeling and make the whole series a really good full fledged GitS SAC and nothing in the second season feels like everything in the 1st season is retcon based on the reception but a plan decided from the beginning. After SAC_2045 i’m confident they can make another really good SAC TV show or movie in 2023. But you have to accept the really bad CGI in the first 8 episodes of SAC_2045 to enjoy the ride ^^

I show my mother Hathaway and she never watched any gundam movie or tv show and she really loved and had no problem to understand what is happening.

As a better entry point I would recommand Witch from Mercury which is the lastest TV show
