Can you list some of the incoherencies? I found that things that seemed odd at first can actually be reasoned out pretty easily.

Spoilers!

For example, a friend was confused how Fischer could be revived. They explained that death with the heavy sedation would lead to limbo, so it could be concluded that dying was actually just a shortcut to go into a deeper dream state, he wasn't actually "dead". When they woke him up from that dream, he came back.

Another oddity I found was that they needed to synchronize all the kicks, wouldn't one kick in the deepest dream suffice? Well, in one level of dreaming if you think you're falling, you can actually feel it (whether the falling feeling happens in the sleeping environment (dude sleeping in a chair and being tipped) or in the dream (dude being thrown out of a building)), but at 2 levels of dreaming, the falling would be too abstract to cascade all the way up.

You probably found different glitches in the movie, but the above shows the process I used to answer some questions.
