I know this is a minor thing, but it cheeses me off too. I'm a fan of the old logos (I'm actually one of the original members of that Closing Logo Group thing) and if you want the movie to be theatrically accurate, the original logo HAS to be there. No question.

Warner Bros. is one of the worst with this practice on movies; most studios will only replace logos on movies (as opposed to TV shows) if they re-release the movie in theaters and/or are doing some Special Edition, but WB has screwed with their movies since the dawn of video. So I was so happy to see the correct logo at the front of Pee-Wee when I saw it in 35mm. (Though even their repertory 35mm of Caddyshack has the later Orion logo - much as I love that logo and think it fits just as well with the Kenny Loggins music, someone should do an HD preservation with the PCM mono mix from laserdisc, and the correct Orion logo at the start...)
