Hmmm...This set is very tricky. There are a lot of pros and cons with this set.
Pros - 1) the minifigs are amazing! You get 2 horses, ring wraiths, 2 hobbits, and aragorn. That is a lot of minifigs for one set! This is one of the main reasons why I would buy it.
2) Nice pieces. This set comes with some great pieces for castle building, the spiral staircase, and the creation being built with bricks, not just bunches of the panels.
Cons - 1) PRICE! This set is way overly priced, I definitely do not like that.
If I don't find it on sale, it is not worth it.
2) Presentation. I don't like how the set looks at all. It is too small, Lego could improve their rockwork, the ruins aren't very convincing, etc. Now this goes for a lot of their sets, but I still don't like that. It isn't appealing to me, like Helms Deep was. The price didn't help.
3) Playability. Ok, I know that Lego HAS to have playability in their sets, but flick-fire missiles? Seriously? That was one of the worst parts that I found in this set. I like being realistic, flick-fire missiles in Lord of the Rings is NOT realistic! The other play abilities were fine, I just don't like the missiles.
I am 50/50 on this set, if you can find it for a great price, I would definitely recommend it. Otherwise, not really.
