"Spy" takes an awfully long run up ..
.. to get to the enjoyable stuff.
In total, the film is enjoyable because the later part of the film is where it comes into its own, but the first part of the film is IMHO characterised by people that want to be funny and go through the "how to be funny" list for aspiring actors motions than actually are, the sort of effect you get when a marketing executive had been told that the ad MUST be funny but has no idea of how to make that happen.
Maybe I'm too used to intelligent British humour (yes, not a fat of Ricky Gervais either), but I had a fight with myself to stick with it for the first 30 minutes. After that it got a lot better so guess all is well that ends well as the remainder was worth ploughing through the predictable first part.
So I'd give it 4 out of 5: good, could do better.
Project T was in that respect more interesting, in a way it made me think of The Age of Stupid that led to the 10:10 campaign.
