First impressions? very slick, great movie clip intro, very nice graphics, good sound, straight into the action. Lots of orcs to kill, atmospheric scenery & sound, visually very faithful to the films.
Then some more orcs to kill, then yet more, then a few more for good measure. Don't expect a deep plot here, this is a good old fashioned dungeon bash. If it moves, hack it, zap it, shoot it, and then hack it some more. Get experience, enhance your character, kill bigger & badder stuff.
But if that's your thing, this game does it very well. The graphics are impressive, the sound is pretty good (FX better than music). The combination of different levels & different character abilities does make each character's game different.
Overall? visually impressive, good hack & slay gameplay but plot very linear, although good character development. Waste of money? no.
