Are we watching the same show? Sure all the ST series and films had their share of explosions and shaking, but they never sacrificed substance for style.
Depth is a subjective matter. Into Darkness projects something actually deep for all the in-your-face explosions and SFX.
We are being presented the idea of a darker side of the Federation, and this is critical, at this point in time, early in the timeline. People speculated about repercussions of the destruction of Vulcan, and here it is. They ramp up weapons R&D and build up because of fear.
This plays well into the positivism aspect of ST. Is starfleet ready to embrace the darkness? Or are they going to see light at the end of the tunnel. That I think is the central conflict of the film. Saying that it isn't deep,doesn't mean it isn't. People just need to focus and not see just the aesthetic.
