Is there anything to learn from Bojack Horseman?

The message I get from this show is that the most important things in life are our connections with other people. This was mentioned in the underwater episode.

Bojack has many opportunities to develop deeper and more meaningful relationships with others. But he consistently squanders these opportunities due to selfishness, ego, immaturity, and his desire for instant gratification.

He always ends up feeling alone. And it's entirely his own fault.
This ongoing personal tragedy is, for me, why it's so heartbreaking and brilliant.

Don’t do heroin.

depression is a bitch?

Life has no plot, no moral lesson, it's just the meandering path from birth to death.

I'd tried to get into this series after hearing good things about it on Simspons boards, etc. I gave up on it after the episode on abortion.

Its dialogue can be very funny, but only rarely; most of the humor is obvious sight gags and plays on the characters being animals (oh, the dog man like the show "Bones", ha ha ha).

The animation in a couple of the episodes was creative and impressive, too; the whole sequence where Bojack, Todd, and the girl were on drugs was amazing, and the underwater episode essentially told entirely with body language.

Those things aside, though, the show is mostly depressing and juvenile-ly preachy. What I've learned from it is Hollywoo(d) is a messed up place full of messed up people who don't have much moral authority to said preachiness.
