I liked it from the first listen, but it definitely grows on you.
Been a big Tool fan since about 2004. Saw them live in 2006, at the age of 16, and then again here just last month. I've also seen APC live when they came to Denmark about a year ago. It's quite amazing how they've managed to stay relevant for so long, and the most impressive thing is that it seems Fear Inoculum might be the biggest selling album yet! With them going on online streaming services they'll also definitely see a boost.
I don't think the new album will eclipse anyting like Lateralus or even Undertow, but it's definitely shaping up to be excellent. I actually really dig the new style. I think I'll like this album more than 10.000 days, barring probably a few tracks like Wings For Marie. Can't wait!!
Edit: Wow, the album is #1 on Amazons CD preorders AND the limited edition is already sould out
Bummer.
