I've watched the Lord of the Rings movies 4 times through. They're brilliant. The storyline is really well done. It is not a big problem in my opinion that there is smoking and alcohol. There is a lot of violence but no blood to speak of. I think the entire trilogy is amazing (see my reviews). My entire family loves the Lord of the Rings. A masterpiece from J.R.R. Tolkein (the books), and a masterpiece from Peter Jackson (the films). I love adventure quest stories and this one is clever, emotional (I cried at the end of the last film) and sometimes preposterous (the riding down a vertical slope scene). It has warriors, dwarves, elves, orcs, huge fire-breathing minotaur thing, wizards (good and evil), a spirit with red eyes inside a huge set of spiky armor wielding a mace, servants of the dark lord with awesome black capes and a ring with elven runes all the way round it that gets heavier the longer you carry it. I don't think I need to review the other two movies, I think this is enough for you to know that I love them and recommend them to anyone who doesn't mind violence and scary scenes.
