I was thinking that too. Although, so far FFIX has the final bosses I've been happiest with, since there's a few to go through and I found them challenging.

Obviously it depends what level you are at, but I think it was just about right in terms of how I like end bosses to be.

I always get confused with story elements sometimes anyway, so I wasn't too bothered about Necron, not to a point where I'd worry much about it anyway.
