I've been 'adjusted'!?!?

For the Adjustment Bureau, please press 1.

I've watched the movie The Adjustment Bureau on its opening day on Friday.
*SPOILER ALERT* Stop reading now if you haven't seen it and if you plan to see it at some point.

There are a few things that are at conflict in this movie. It seems to promote the belief that there is a God and He is called 'The Chairman'. He has a plan for everybody and to make sure His plan gets done, He has 'angels' with hats who look after EVERYBODY.

But the premise that God is omnipotent is undermined here. The movie is saying that God's plan could fail. I agree with that, because I want to think that we do have free will, so if God's plans fail, it is because we freely chose not to follow God's plan for us. That's all good, except for the angels sent to monitor us poor mortals. God's angels are powerless. They are tired and fall asleep on park benches, they can't carry a simple task on time and they use doors to get from one place to another. Even better, they have books to document where the doors are. Also, poor them, they cannot use the doors without their hats!

Imagine, angels with hats, not wings! They can't even fly! They look like humans!And they are seriously understaffed. I think I can wrap my head around the fact that God has helpers, to carry out His plan, but God to be understaffed? Also God is omnipresent, so He knows what is going on at all times, He is watching. Then why are there angels to monitor us ALL THE TIME?

And what about the ripples? In the movie, the angels wanted to stop Matt Damon's character at all costs. He was running away from them, and to try to stop him, they created a minor accident....
What about those people, where were THEIR angels?

I believe in God. I believe in his omnipotence. I sometimes question my faith, but I always go back to it even if I can't understand or prove anything. I understand the creative and artistic effort of the movie. But surely they could have given more credit to the angels?
It's always fun to analyze how people picture God, and how faith works in people.
The movie itself isn't bad, but it does build up on expectations and then has a flat finish. 
Enough said.
