How do you take top-tier action-movie actors like Vin Diesel, mix them with other reliable box-office favorite actors (Elijah Wood and Rose Leslie, fresh off her star turn in Game Of Thrones) and a smattering of box-office greats like Michael Caine and NOT have a winner on your hands? This had the look and feel of a guaranteed profitable franchise! What went wrong? Too much CGI, Vin Diesel's one-note performance, sub-plots going nowhere,...and the final chapter/plot wrap-up pretty much killed it for me. Makes you wonder if the production team realized this wasn't the hit they wanted and re-wrote the end to cut their losses?
