The "Doors ~Yuuki no Kiseki~" PV reminds me alot like the PV for "Love Rainbow" - maybe it's the forest-ish scenery of it all.

But it's looking so beautiful!
"NOW or NEVER" also gives me a "Troublemaker" vibe - but the PV's looking very cute & fun, so far! Arashi sure know how to excel at that fast-paced choreo.
