The facial animations and lip syncing for vocalists on several RBN songs are poorly presented in songs. Examples..
In the song "Packet Flier" by Terrorhorse, I know for sure the vocalist is suppose to be screaming their ass off with wide mouth animations and eyes closed at very intense parts of the music, but instead I'm treated with a vocalist with a non-emotional blank stare and lips that look like their just mouthing the words to the song, not screaming at all.
In "Even Rats" by The Slip, it's the same non-emotional blank stare through the song. Also, during the "Woooah, Woooah, Woooah" parts in the songs, the vocalist's mouth is just opened through the part, not trying to move their mouths to make it seem like they're actually saying "Woooah" and such.
All I can say is, that's a huge letdown for me. It's awkward to see such animations and even my friends tend to point them out: "What the heck? Shouldn't the singer be screaming in this song?"
