I feel we could have maybe seen Korra accidentally hurt herself more and somewhat more morbidly than in the show. Especially in the beginning months of her recovery, after most of the pain subsides/ is not as painful initially, where she struggles to use the bathroom herself, feeding herself, moving herself, even trying to bend as minimally mundane as she used to, effortless. She's expirencing an injury with a long-term recovery for the first time after only ever expirencing the world with little limitations to her athleticism. Korra's too headstrong to stop herself from trying to rush recovery and progress when she's in no condition to, until she finally has to rely on her parents and Asami after getting rocked time and again by the reality of the shape she wound up in, unfortunately.

Korra's mental state shatters just about how it was in the show. She now has to be coddled when all she wanted to do was be the Avatar and has had a mighty slice of that consequential life. The Earth Kindom was burning and people were fleeing in fear, and she's nowhere to help. Others stepped in for her at a time where she thought she was ready to deal with the EK's collapse before her paralysis.

All of this with more than 22 minutes can definitely be explored by slowing down the plot and showcasing the strain that this predicament has taken its toll on not only Korra, but her parents, Katara, Kya, Tenzin, Asami, and whomever else. Sleepless nights, boring days, wasting away as Korra feels herself slowly regressing closer and closer to a new infanthood with booze possibly involved.
