Yeah, no. Even if they try to make the dad seem likeable and redeem him with this whole "he is just like that, but still tries his best", it is still a fact that he abandoned his son and now his 3 daughters. There is no excuse for something like this. Even if you are a person like that, that wants to go on journeys on a whim, you still have to take responsibility for a lot of things. And especially for your children. Excusing abondening all 4 of your children with "I want to see the world and experience it" is just shitty and irresponsible. He shouldn't have had kids in the first place if he was going to be like that.
