I was surprised at how much I enjoyed this show - despite being so old, Tetsuwan Atom still doesn't lose in terms of plot. I watched some episodes of the older original version (from the 60s) and the episodes have similar stories so I think this remake does a decent job of maintaining the storyline and keeping things interesting.
I also like the small differences (like how he got his boots, the way he and his father were separated etc).
The only thing that I think is kind of weird is when they put so much emphasis on the show of how he's a robot, but then expect him to feel a certain way when they call Atlas his brother. ...he's a ROBOT. you guys aren't brothers, you guys were just built the same way. In that vein, anyone could be your brother XD lol I just thought it tried being too serious and it felt kind of silly. Otherwise good show.
