Title: Messing with a classic
Review: Despite having reasonably good video (for a public domain release), the audio has been "enhanced" by the manufacturer. In other words, they've added sound effects in addition to the original soundtrack (and occasionally over it). One can certainly understand issues with the opening and closing credits, given the ownership changes of these old cartoons, but crassly adding sound effects is akin to sacriledge. Do yourself a favor and wait for a better public domain release or a full restoration by Warner Bros.
