Like the 1st movie, I thought the sound design in ROTF was top knotch. I saw it in IMax and it was probably the most badass movie sound experience to date. I didn't like how they "unprocessed" Starscream's and Megatron's voices as I thought they were perfect in the first one. Prime's voice was a little weak too, compared to when he first showed up in the 1st movie. Soundwave not have at least some vocoding sucked, but Dr. Claw was still effective. All in all though, I thought the voice were decent. A pass. The effect sounds were great. Detailed. A true "wall of sound". Bot noises were awesome. Really amazing. I can't wait for the Blu-ray. Paramount doesn't do DTS, so I am hoping for my first Dolby TrueHD track in 7.1!! Fingers crossed. Sound is 75% of the movie experience for me. This one is going to SHINE!
