I agree wholeheartedly, but I think you are referencing episode 5. Episode 5 was great, but like you said, it could lose a good 15 minutes and be much better off for it. Episode 4, on the other hand, was impressively paced and had me on the edge of my seat.
Oh sorry, I had episode 5 freshly on my mind and misread lol. Yes I would agree that Episode 4 definitely has the least amount of fluff in terms of all 5 episodes.
