"Tekken 2: Kazuya's Revenge" is technically a prequel, but it doesn't even fit within the continuity of the first movie and somehow manages to be an even more unfaithful adaption of the video games. Even worse than that, it's REALLY, REALLY boring.
“The Hobbit: Battle of the Five Armies” feels less like a movie and more like the third act of a movie, being almost entirely based around a single awesome battle. You might find it to be shallow...because it is...but it's certainly not 'slow'.
"47 Ronin" sounds like it would be quite the lark, either as something ludicrously epic or ridiculously stupid, but entertaining all the same. Yet I can't say I ever really enjoyed myself during my viewing. The film isn't especially terrible, it's just kind of subpar and dull. At times, I WISHED it would become atrocious simply so I could feel SOMETHING as I endured it. But a las, I was overcome by its blandness.
"The Hobbit: The Desolation of Smaug" is about as 'good' as part 1, but before detractors start groaning in disgust and giving up on the flick, I actually think you might like it. Of the entire "Lord of the Rings" franchise, this easily has the fastest pace, never letting the viewer catch their breath for about 3 hours.
I actually like “The Hobbit” more than the latter two sequels because it is a return to what I liked about the original. Yet I also can't deny that it is the most flawed of the Peter Jackson-Lord of the Rings adaptations.
