Anesthetize is good....I personally think Arriving Somewhere is not only VASTLY superior, but may in fact be the greatest concert film I have ever seen PERIOD.
My favorite part is the visual effects...it just gives the whole think a very old fashioned "concert film" feel...like what you used to see in the theaters in the 70's and 80's. Add to that, the setlist is much much better... Arriving Somewhere is the only concert film in my collection that I watch over and over again and never get tired of.
Believe me, as a film aficionado, I think Arriving Somewhere... thanks to Lasse Hoile's signature visual style seen in his visuals is what gives it its charm. It's looks a bit more experimental, and IMO a bit dreamy like; something you'd see in a David Lynch movie. I might even call it an arthouse concert film. I agree that the visual effects are awesome even though there's a minority who've openly criticized it.
Anesthetize as well as the other two concert DVDs Lasse Hoile directed, SW's Get All You Deserve and Anathema's Universal I would say were more in the "traditional/professional" way of how concert videos are shot and visually represented on screen. For what it is, in terms of capturing the band and the performance, I think they're superior IMO.
As far as the bonus DVD on the limited edition of Octane Twisted, due to way less cameras during filming and the lack of input from SW (from what I read in interviews, Gavin appeared to be more involved with it than SW was, he only caved in and gave his seal of approval despite admitting that he initially disagreed about releasing it) it wasn't the best visual representation of the band, and seemed rushed IMO. But from a historical standpoint, it's great that the last PT tour (as of now) was archived in some way.
