This is a hell of a non-issue, I know, but that's just the type of guy I am.
With "The Hateful Eight" QT broke the chain of two-word titles ever since Reservoir Dogs. I remember when the title of TH8 was announced, I was hoping the "The" would eventually be dropped, but, alas.
Having said this, I googled around trying to find out if QT had intentionally gone for this two-word title thing. A lack of results leads me to believe he hadn't, so for him suddenly going three words with TH8 probably didn't even register.
Don't know how others feel about this (if anyone noticed it at all) but I find it a bit of a shame.
