I have no problem with action in adventure games. Early adventure games like Quest for Glory, Conquest of the Longbow, Monkey Island series, Fate of Atlantis, Full Throttle had action. The most unique adventure game of all time, Dune 1, even had strategy elements.
Problem about Dreamfall's action is that it feels incredibly clunky & is just filler. But luckily most of the time it can be bypassed with stealth.
