Occupation: Rainfall at least proves that the passion is there from an Australian cast and crew to deliver a no-brainer action film as big as Hollywood could do.

We've seen this all before and it feels so frustratingly derivative. Which is a shame really as Luke Sparke's sequel should have been so much better.

The issues that plagued "Occupation" remain in "Rainfall," but there is genuine effort supplied to make a proper blockbuster with action and aliens this time around, keeping this unlikely franchise going.
