I personally am not disappointed, but I definitely see your point and can understand it

To me, there's really no way to tell if the creator made a flashy level to "appeal to their audience" (even if it seems like it) or if they just think it looks cool themselves, so I would not judge that myself, as I feel that calling a level "attention grabbing" is definitely a negative trait.

I do get why you and many others don't enjoy flashy levels as much, though. I do think some levels go a bit too overboard with effects.
