Worst thing I've seen in awhile. Skip it.

Of course, Gilliam’s quest to make his Don Quixote film mirrors the original novel, and the movie he finally made is like a funhouse mirror version — filled with wonderfully, sometimes disturbingly strange imagery as tragedy meets comedy meets romance meets the noble glory of the artist sacrificing nearly everything in the quest to make lasting art.

And so while Gilliam has undoubtedly made better films and certainly greater films than The Man Who Killed Don Quixote, there is something about the ridiculous effort and mixed results that make this arguably the most Gilliam-esque. For anyone struggling with whether to give up, concerned that the result will not match the effort, Gilliam seems to be planting a flag — or more accurately charging a windmill — to say the effort is the reward.

The experience of watching it, especially given its dreamlike unreality and head-scratching punnery (this is a deeply unfunny movie) is like listening to a doddering old man for whom every story — about art, politics, local goings on — ends up being about how every woman is an evil witch that can’t be trusted.
