Close to Greatness

To make up for my last post, which was fairly boring, I've decided to add another boring post. I want to figure out why some movies seem to come close to greatness, only to fall short and disappoint.

If you've seen any of these movies, feel free to share your thoughts on why they seem almost hauntingly good but ultimately fail.

"Where's Marlowe?" (noir spoof)
"The Chumscrubber" ("Donnie Darko" imitation)
"The Illusionist"
