Regarding the LED wall, yeah, it was more obvious here. It felt like they were entering one of those gimmicky project-Van-Gogh-art-on-a-warehouse-wall tourist traps.
The episode where Uhura and Hemmer were trapped in the engine room was another one that stood out.
Makes perfect sense when you realize that T'Lyn (named after her) was another passive aggressive Vulcan that provides comic relief was introduced in "wej Duj".
