You can just turn down the volume.
The puppet Yoda used in TPM was always lame, I'm glad it got replaced. As for the Krayt Dragon call, that's been messed with in every release. The 97 version was different, the 2004 version was different, and now 2011 again. I'm old school and like the original the most, but it's a personal preference thing anyway.
At this point, it's almost become a game to pick out the changes made in each release.
Besides, can anyone say the 2004 Jabba in Ep 4 wasn't a massive improvement over the 97 version? Ugh. Ditto Ian as the Emperor in ESB instead of old woman/monkey face, or the Wampa.
I do think the theatrical releases should've been included as well, but that's Lucas.
