What did you enjoy about it specifically?

I felt her 'cracking' the language was a little preposterous, just all of a sudden 'Oh, I know what you're saying now'. Perhaps it came from the physical contact with Abbot but that wasn't entirely explained so it felt like a bit of a reach to move the plot on.
Also, I'm fairly sure that following the explosion 'Abbot' actually referenced 'Costello' when talking about his injury. How would he know what he had been named when they couldn't communicate with each other? Seemed a bit bizarre but a relatively minor point.
With regards to the future plot twist, again that just felt a bit ropey, it's the main point of the film fair enough but just didn't do it for me.
In terms of character development, maybe I'm being a bit harsh as the plot twist may have been the reason why it felt like they were keeping parts of Adams character back. Again, it felt like a bit of a reach for her to all of a sudden fall in love with Renner but perhaps I'm not picking up on some nuances there in regard to visions she had seen and how that may affect her.
It's a shame as I do really enjoy these films on the whole, but with this and Interstellar I haven't been able to enjoy them as much as I want to.
