As a huge, huge fan of the first two movies, my anticipation was high for the third (and unexpected) instalment.
How incredibly disappointing it was to sit through such a disjointed, laboured and often nonsensical 90 or so minutes. Aside from a couple of mild chuckles, humour was often forced when not missing the mark completely. Characters were thrown in and out of the plot almost completely at random. Many scenes lacked context or even made any sense and stumbled clumsily from one to the next in almost amateur fashion.
My recommendation: wait for it on Prime if you want to satisfy your own curiousity but it definitely goes down in my book as a Greek tragedy.
