Well clearly they are ok with a limited amount of people controlling the trivia and faq etc and getting wrong all the time

It's fairly simple, really. The only time I've ever had an issue with creating a page is with an obscure title in which its year of original release is unknown, and even that there are ways around. Although I do agree the "subtype" should appear on the previous page.

I haven't found it to be all that difficult or troublesome, when I had adequate information to meet the requirements. Then again, I've only created one title, thus far. I didn't even think about how many "check these updates" clicks I had to do.

Does this site actually want to deter people from creating pages?
No, but they only want people to add title pages when they have enough information to meet the minimum requirements
That's why it seems so complicated to add a title page.
When you've done a few then you know what information is required and you can prepare it all in advance. Then adding a title page is much easier
