I just finished watching the third season. I grew up watching the original. This is completely different in some ways, but they manage to retain the best parts of the original, while charting their own new territory. They give us new reveals about the robots and Will's relationship with him even into the last episode. I found it to be an incredibly satisfying series to watch. We see character growth throughout with all the major characters and even some of the secondary ones. Hopefully some day we'll get another well conceived 3 season story arc, perhaps set 10 years in the future, since the kids will be older. They certainly left things open ended enough to do that.
