In "Things fall apart" what are the merits and demerits of Igbo culture?

Of course the answers depend on one's perspective, and the lack
of the ability of one side to see each other's merits is what leads to most of the conflict in
the story.

The Igbo culture appears to have a great deal of festive
traditions, a powerful emphasis on hospitality and family ties, and they have a powerful
narrative of their place in the world and where they fit in.  They have a way of dealing with
death and difficulty that is very different than the western/christian way the missionaries
approach it.

Some of the harder to understand from a western
perspective aspects of their culture might be things like leaving baby twins out in the forest to
die because they are seen as evil.  Another might be their relative acceptance of some domestic
abuse, we see that Okonkwo is known for having a bad temper and sometimes hitting his wives, but
though it is frowned upon, it is accepted.
