The only negative thing I have to say about S5E1 is that the set pieces still feel dramatically cheaper than the S1/S2 sets. There was a sense of environment in the first two seasons, of largeness. Look at the courthouse scenes in S1 when Oliver or Laurel would mount the steps to the entrance; it looked and felt like a real courthouse, there was so much environment, and the set was so big. Now compare that to the city hall set we got in S5E1, when Oliver gave his press conference at the end. TBH it felt tiny. Another thing causing this is the number of extras. In S1, throngs of reporters would flood the scene, again reinforcing the realness and bigness of a scene. In Oliver's press conference, there were like ten reporters total standing on the sidewalk. The same goes for the gala at the beginning. I know it was supposed to be at the police station or something, but it felt so small, so constricted. Compare it to some of the parties that were held in S1, even at Queen Mansion. Those felt so much bigger, so much more like formal events. I don't know if it's the camera work or what, but nothing in this episode really felt big.
So this is one thing I hope Arrow can fix. It's a minor thing, but it was my only real complaint with the episode. I think this problem really started last season, because S3 still had that sense of scale, of realness, of largeness. Everything felt real. The city, Nanda Parbat, the warehouses, they all felt like real locations. This episode, I felt like everything was a set, y'know. There's very little ambiance; it all feels lifeless, fake. And it's so small. I would bet that the show's set budget got reduced or something, which really is a crying shame. This one minor issue, if it had not been present, would've made the episode really feel like S1 back. And from an acting, writing, and action scale, it really did feel like S1. But it felt, at the same time, very constricted, because of the smallness of everything.
