Compare Kylo Ren's scene with Han Solo to Anakin and Obi-Wan's on the landing pad on Mustafar then get back to me.
Oddly enough, I knew exactly what was going to happen in both scenes. In one it's because it's a prequel, so I knew where all the characters were going to end up. In the other it's because they wrote it and played it so obvious that it took away any sense of surprise. As soon as I saw the catwalk, it was like, oh Han's buying it here. Poor setup job.
When he gulped in relief you didn't think that was funny? It wasn't fall on the floor can't breath hilarious but I laughed the first time and still smile these days.
When the Falcon jumped to lightspeed and Piett just stared with a combination of disbelief and dread at the empty space, I was thinking he was dead meat. I was almost grabbing at my own neck waiting for it to happen, anticipating it so much that when Vader just walks away, I felt a sense of relief. The combination of how that scene was played out and acted managed to put me in his shoes. I never thought there was anything comic about that scene at all.
