I rarely do negative reviews, because of two reasons. One is that I prefer to show good books worth reading than the other way around. The other is that I usually put them on my virtual DNF shelf. I make an exception here. It took me a long time to read this book as it needed an increasing amount of effort to go in. 
 Here is goes: 
 Being influenced by a good writer is OK. Gathering most of the good scenes, changing names and reordering a bit is NOT OK. 
 OK. Let's see: 
 (view spoiler)[ 
 - A wizard/druid goes into the Shire/small town to ask for help from local, peace loving and isolated people to help save the world from a Warlock who wants to conquer the world. 
 - Said Warlock already tried this before, but was defeated in a great battle when different species united. 
 - He also lacks conventional physical form. 
 - He was once a good being, but got corrupted. 
 - He starts to regain force somewhere in the North. 
 - And gather army made up of "bad" fantasy creatures. 
 - There is a magical item, a Ring/Sword that can be used to destroy him. 
 - The Warlock send out his undead Nazgul/Skull bearers, to search for the one who could use the magical item. 
 - When these undeads are near, everything is frozen and terror permeates everything just by their presence. 
 - One of the first direct appearances is in an inn, where the main character and his sidekick sleep. 
 - The main character, Shea, has a sidekick who is, "simple", but has unquestioned loyalty toward his master/brother. 
 - Soon after setting off, they end up in a big forest and get into trouble. 
 - They have to cross a swamp, every living person dares to cross. 
 - They encounter a monster with tentacle emerging from the depths. 
 - One member of the party gets injured+poisoned and only wakes up later in a city along his friends. 
 - In the city where there is a council to decide what to do. 
 - A special party is assembled to set out for a journey. 
 - It is made up if men, elves and gnomes and a half-elf who just wants to be home. 
 - The party is lead by the wizard/druid who knows a lot more than he reveals, but the party members decide to follow him, as he is still the one who know the most. 
 - Along the way, they have to cross some big mountains. Although the wizard/druid doesn't like it, they avoid the pass and choose to take a route through a city within the mountain. The ancient city is dead and the route perilous. 
 - Within the mountain, they encounter a monster and they can hardly flee. 
 - The wizard/druid falls into the depths with/of fire and thought to be dead, but returns strong. 
 - Gollum/Orl Fane shows up, who is obsessively attached to the magical item. 
 - He is small and lurky. 
 - Two/one of the peaceful party members are captured by orcs/gnomes and the party tries to find them. They stumble upon a scene of battle aftermath. 
 - They find out that they are/he is not dead, but probably escaped. 
 - A member with good tracing skills confirms. 
 - In one of the important kingdoms of the world, a (de facto) king's mind is poisoned by a conspirator who make the king see friends as foes and mostly get rid of the army that could stop the evil army. 
 Minor ones scattered: 
 - Frodo/Shea has an item that emits light and evil things are frightened/banished. 
 - A spider like creature attacks Frodo/Shea, who almost dies and is unconscious for a long time. 
 - Sam/Flick running around in a tower in disarray. Orcs/gnomes dead or fleeing.

 One "big" difference: While Tolkien's is partially meant as an origin myth for the British region and happens 'before our history', the Shannara chronicles happen 'after our history'. Bang! Whole new story :D 
 The story has a strange, periodic/alternating style. Story-description-story-description. These are usually clearly separated. Story goes on, then comes a length description, (simetimes several pages long and often not necessarily connected to the story line), the back to story that goes on without change. Less descriptions and a better synergy would have made a much nicer story telling. 
 Again: There is nothing wrong getting inspirations from others. It also difficult to write an idea or scene that has never been written somewhere by someone. But this LotR recycled with an inverted timeline.
