Feels like playing Finding Nemo or some kids-themed adventure game.
The combat system is unchallenging overall and thus makes the player bored easily, and the stealth factor (mostly the hobbit) is very forced. Maybe hardcore classic adventure fans (Dreamfall, Gabriel Knight...) may find this level of action mildly exciting.
Though I must say that the overall plot follows closely to the story in the film, which may be the only console to LOTR fans who must have this game.
