I do not disagree, but I believe that most people would be satisfied if a good database was created with the most common fields used. If enough people start using it it might be about as good as any other service. A web crawler to dig up the data from other sites is also a possibility, but there might be legal problems as discussed before.
Anyway, I hope a more automatic solution is implemented soon. You can't expect all video and series watchers out there would want to set up the PVDB app, plugin and excel to do the job. I will my self, but I'd be much more comfortable with a built in solution.
