Summarize the following movie reviews:

1. The City of Lost Children is a stunningly surreal fantasy, a fable of longing and danger, of heroic deeds and bravery, set in a brilliantly realized world of its own. It is one of the most audacious, original films of the year.
2. Lyrical, strange, gorgeous, and pretty darn hypnotic.
3. Falters under flabby direction and a weak script suffering from too many ingredients and not enough cooking.
4. Anyone looking to lose themselves in an engrossing fairy-tale world will be richly rewarded.
5. A visually stunning and intensely bizarre fairy tale.
6. A freakish visual delight
7. Watching the film is like leafing through a giant sketchbook crammed with intriguing ideas that can't all be comfortably fitted into the same master plan.
8. By turns funny, horrific and oddly sweet, there's really nothing out there that's quite like City of Lost Children.
9. The City of Lost Children is as visually striking and daringly offbeat as its predecessor.
10. Many people will probably not find themselves sympathetic to this movie's overachieving technological pretensions, while others will find it the best film in months or years.

Summary:
Not all of its many intriguing ideas are developed, but The City of Lost Children is an engrossing, disturbing, profoundly memorable experience.
