They didn't seem to really think through the locker layout or process. The configuration is confusing with multiple blind corners, it's extremely congested, and guests here aren't familiar with the whole "everything in your pockets needs to go in there" standard. Unlike Velocicoaster, there isn't adequate, sequestered space to wait for the metal detectors, which kept getting backed up and worsened the overall congestion. It's actively unpleasant, and I don't see a quick way to resolve it other than "admit fewer people at once."
