I really enjoyed this - For some reason, I didn't think I would.
The characters were real, relatable, and interesting. The story itself kept my attention and I was rooting for the mom.
The opening scene is a tad long I feel, could be tightened.
You haven't listed it as a comedy, but I think it has light-hearted comedy elements - a dramady I guess.
I think the emotion could have been ramped up at the end - This is a struggling mom, she has fucked up and blames herself, most parents have been there so that's very relatable. She gets reassurance from these strangers that she is a great mom - so far so good. I guess I wanted to see a subtle reassurance from the kid at the end - you know, a simple hug of the leg and a "Love you mom" - as a parent, that would have heightened the emotion at the end for me - because at the moment the ending is more about the relief that she fixed that problem, rather than a final show of "yes, I am a damn good mom" - does that make sense?
Anyway - just my opinion, which could be a load of nonsense
Best of luck with it
