A movie is what the most of it's run time is about. MIF is not about action, or jokes, or anything that's fun, really. It's about convoluted, dumb spy plots and pretending that a man near his 60's is a few decades younger.
Like watching a man vomiting. It might be the result of some very intricate and interesting internal processes, but since no one shared those processes with me, I am left with only vomit. And don't watch it if you have epilepsy.
