The deleted scenes were needed!
This movie is good. But the deleted scenes make it better and add a lot more to the story that makes it sensible.
The scene with Jacob meeting the chemist in his apartment showed him facing his demons, and expanded the role of the chemist and his ladder drug. It made more sense why he would want to help Jake, so he ended up being an angel.
The scene with Jacob buying a ticket to Chicago showed he wanted to escape, and the "dream on" voice holds significance later on when he is in hospital. Without it it just doesn't work.
Finally, jake seeing Jezebel revealed to be himself was incredibly important, it explained the whole movie and why he was suffering.
Why Adrian Lynne decided to cut these scenes is a wonder to me. Without them, the film is a lesser product.
Limit of the Willing Suspension of Disbelief: directly proportional to its awesomeness.
