I found this game to be very fun. Sure, its a bunch of button smashing throughout the whole game,but that doesn't stop it from being great.

The Good:This game has an excellent storyline[in my opinion]of both good and especially evil.
The game's controls are simple and easy to use with cool combos to kill your enemies with.
The heroes are pretty good,I think that being able to play as Sauron is a cool improvement from other LOTR games.
For vehicles on good you can play as Ents,and as bad you can play as Trolls.They are REALLY powerful,and can heal themselves and others,but they do have their weaknesses.
The multiplayer I found the best part of the game. It's easy to get kills as archer,if your skilled with targeting,or a mage with their firewalls.Scouts are good since they can instant kill enemies with their Backstab move.And warriors,well pretty much just run in there and start hackin away!

The Bad: It's not the greatest in graphics[but then again we're just in it for the evil campaign,right?]
It has some issues with connection problems on multiplayer[as thats what I've seen.]
The lives thing on the campaigns can get annoying if you have trouble on certain parts.
It is actually quite easy,at least on heroic.

Other than that,I think this is the best Lord of the Rings war type game in the series.I strongly reccomend trying it.
