This summer's movie nitpicks: Pacific Rim, Elysium and Man of Steel

Movie plot holes just sit there taunting me. I need to bitch about them. Sadly my ranting lacks any particular humour value.

Pacific Rim

The obvious nitpick of this being ridiculous is invalid. Rule of Cool says giant robots win over realism. I can even accept that they'll believe that a wall might work and justifies winding down the expensive armaments programme. Politicians are idiots.

Elysium

The rich go into space and the poor are stuck on a polluted earth. Meanwhile the rich live on a space habitat and have magic health care machines in every home.
