Most of these things have awful plots. As yet, the AI systems used are not very good at plotting. If given a screenplay and character sheets, they can do reasonably well. But the "generate a 60 episode drama from one prompt" jobs are not very good. This is more of a problem with the Asian drama industry than the technology. There are not that many different plots.

The visuals are consistently good now. If you put in a decent script, there's a good chance of getting something good. The script has to tell the characters what to emote. The automation isn't good at that yet. Nor are the vocals good at all.

Give it six months.
