I enjoyed both Hotman 1 and 2.

1. Maybe the best thing is that we see "A Totally Voluntary Family". A very young man raises a newborn, found with a note claiming that it's his kid. Besides, he invites 4 of his half-siblings who have problems with their other families. So, a family of 6 that could've easily lived separately.

2. And the worst side of the drama should be about this brother's character (treating everyone else as a little kid, using physical strength, meddling in others' private life, ...). Still, in the end, everyone's smile and happiness is his ultimate priority, so he's smart enough to notice his faults, apologize and fix them up. Also, it's good that the younger siblings keep their grounds more or less. So as a typical J-drama of the 2000s, we can see this 'peaceful' clash between the old paternalistic culture and the new generation's penchant for freedom & independence.

Overall, a nice heart-warming family drama with a supercute, adorable little kid, 'Nanami'!
