No pun intended - and certainly no innuendo behind it. If you see one that is on you - all kidding aside, let's dive into it. I have not yet seen the Japanese original - the one that is based on the real story about the dog Hachiko (the dog seems to have a different name here too and also is a different breed if I got that right from other people) ... I did watch the US movie with Richard Gere though.
I kinda liked that one too - I reckon I am a bit of a sucker for anything with animals in it! Though I think I have to re-watch Marley and me, that did rub me the wrong way. Here though you have a Chinese version of the story. And I understand if some people take issue with that. If you are one of them, maybe it is best not to watch the movie at all.
For everyone else, the story is gripping and the telling of it will bring you to tears ... nothing surprising in that sense. Anyone with a heart beat will feel something watching this surely? Not calling you Shirley! All kidding aside, very well acted and well edited too. Great cinematography ... and score! Really well done overall! With great family scenes too ... everything you need! And if you ever had a dog ... you will understand ...
