I think the 90210 reference is a bit dated, maybe for something in the 90's but that show has been off the air for so long (8 years) it is losing it's usefulness as an insult - yeah there is a new version but it sucks, and does not have the wide spread pop-culture acceptance that made the original such a good reference for all that was wrong with the world. :unsure
There must be something new to represent the new 20 something crowd, something that sums up the fast cut action scenes that make it hard to watch a fight and know what is happening. Although i think it is style over having to pay for a good fight coordinator, it is a hip-young-film maker type of thing and would be more relevant to a slam against someone trying to appeal to the masses.
Hmmmm...
