Yes, this is the best in the series. I really like how you add a lot more parody to it. In fact, with each installment, you had more going on added. I haven't seen that animated Return Of The King. I am not interested in it. I loved the Nostalgia Critic reference. That titanic movie was at one point the worst film of all time on the IMDB.
The Snickers bar talking makes as much sense as anything else. Imagine how much power a full size one would have. I like your apology to those with diabetes at the beginning. The powerup scene was funny too. That...thing was sure easy to kill.
