Too long, but very sweet.
<em>'Hi, Mom'</em> is a film that holds a lot of heart thanks to how serious it can get plot-wise, though as well manages to blend in a fair amount of comedy too - the language barrier on my part does probably hamper it slightly as you'd expect, but even I got some chuckles out of it.
Jia Ling (also writer, director) is front and centre throughout and puts in a good performance, the latter also goes for Zhang Xiaofei, Shen Teng and, in a smaller display, Liu Jia. As noted at the top, I did find the run time to be overcooked; not convinced this needed to be 2 hours in length, personally. That's my only real criticism though.
The score is well done, some bits kept reminding me of the music from <em>'<a href="https://letterboxd.com/film/toy-story-2/" rel="nofollow">Toy Story 2</a>'</em> for some odd reason. Not that that's a bad thing, nor is the film itself. I had a positive time watching it and that's all you can ask, really.
