1. Part I was REALLY slow. It's mostly a lot of "setting the stage" where you meet the characters and it's kind of compelling if you're a history nut since there's a lot of scenes involving depictions of medieval life and times as well as some background on the massacre of Cathars. Basically Part I sets up "the mystery" but it was so slow-going at one point I asked myself how could they possibly tie it all this together in another 1.5 hours? and therein lies problem #2...
2. They Don't.
Part II was REALLY fast and had no plot. It almost came off as if the producers really wanted to make a sincere historically intricate film but ran out of time or budget and basically slapped a bunch of scenes together that kind of made sense, and called it a day. In part I, you learn about Alice in modern day and that she shares some psychological connection with this woman Alais in 13th century France, and that's it. In part II, so many other parties/characters are thrown into the mix that lead nowhere- there's the villainess head of some order centered around the labyrinth, the potential love interest but his storyline isn't really developed, and then some religious nut who keeps butting in and bad sibling rivalry, the introduction of John Hurt's character...it was all very slapdash and clumsily put together. The Deus Ex Machina of the plot really took away from the storyline which leads to my main problem #3
3. YOU NEVER REALLY FIND OUT "THE MYSTERY OF THE GRAIL"! Ok, well you kind of do, but it was a cop-out, muddled, poor excuse for an answer and it in NO way answered the mystery that was posed in Part I. In Part I you are introduced to the Cathars and you learn about a mysterious Muslim who is the "navigator" of an ancient religion requiring all three books to be brought together at a certain date, so they can be deciphered and some magical event can take place. Basically I'm sitting there thinking the damn cosmos is going to realign like something along the lines of The Fifth Element, and the retard screenwriter throws some low budget ABC family crap ending for viewers to lap up. NOT IMPRESSED. And it wasn't just the main mystery, there's so many subplots that's never solved/explored- there's a dead body introduced in the beginning but it's never really tied to the rest of the story, the evil older sister is out to get Alais but you never figure out how/why she knows about the order etc, what was the point of Alais's husband in the story? What was the point of adding Draco Malfoy's useless character? (and is it just me or is he just as whiny when playing a good guy?) Why did the bad crusader who was after the books all of a sudden just...stop? Yeah. It's one of those films...SMH....
Overall, it's just the kind of thing you should expect from regular basic tv, low budget and poorly cobbled together, which is pretty much all of the CW, but at least their regular lineup hits the sweet spot in whatever low form of entertainment you indulge in, but this labyrinthine convoluted mess won't push any of your buttons, whatever buttons you may have. Not for romance, not for action sequences, not for twisted ingenious plots, not for ending, not for history and definitely not for acting.
