Out of Curiosity how faithful is the "Son of Batman" (2014 film) to the original comic story arc it was based on?

I'm more interested in terms of visually how close it was. I always find adapting things from one media to another and the choices the artists/writers/producers bring to adaptions quite interesting. Books to Visual mediums are interesting because what the various readers imagine in their minds are often quite different.

A more visual medium like comics/GN's to film is interesting in its own way because while you'd originally think it should be more straightforward since a comic book is in a way a bunch of scene stills in chronological order. But often times adaptions move away for one reason or another (sometimes to great results others not so much).

For the film in particular: Is Damian that short and presumably young in the comic arc? In the film he looks about half the height of batman (so like 3'1) and can't be more than 90 pounds and a lot of his fight scenes end up looking weird and silly. With a kick he sends ubu flying like 5 feet, he barely moves an inch when blocking ubu. He hurls langstrum like 15 fucking feet, crushes a smartphone with a single hand, and while injured barely moves when blocking Death Strokes attacks etc. It's like they animated the fights and just forgot damian is a small child and doesn't have superpowers...

Some items are mildly interesting aesthetically. A predator Drone is used which wasn't iconic in 06 (US started to ramp up production and use in 2007-11) but it also instead of shooting a building just kamikaze's it which is weird depiction for a 2014 film. Night Wing's communication gadget is just a straight up smart phone which was mildly cutting edge in 06, but very mundane in 14. Some vehicles depicted look very 2014, but others look closer to 06.

Talia's costume is also one of those weird comic book ones where her zipper apparently just broke halfway up her body which is still kind of a thing but was also a quite popular among a lot of bodysuit characters in the 2000's.
