Strong Points:
Nice world
Great story with emotion and consequence
Good sound and art direction
Hacking is great fun
All items are usable and helpful (blackout is the most original)
Varied mission types (mostly)
Online is fun
Nice, varied characters - most of which you end up caring about
Just looking into people's lives and actions is really immersive and detailed
Controlling another character's movement via a camera is fun...
Lots to do
Easy to go in all guns blazing or stealthy - both are accessible and fun to do
Gives lot's of scope for sequels
Weak Points:
Some story arcs were a bit predictable
Can't upgrade weapons
Run out of new hacking options quite quickly
Handling of cars is a bit hit and miss
End of mission normally involves 'kill all enemies or escape'
You have a hacking phone but can't use it to ring up characters like GTA V?
...although it would've been nice to have been able to control their actions e.g. shooting someone, as well
Linear storyline in the sense that you can stealth your way to the target but if the story calls for a massacre, a massacre is what you've done
NPC's seem to think your really dangerous and run away or think your weird and run away, just when your driving or running
Ubisoft's famous optimisation
Nitpicking:
When you rebind a key it doesn't rebind the hint for using it
When you are on the smartphone or choosing weapons while moving, the keys are the same so accidentally clicking something is common
Can't turn off news bulletin in car
