Research: Comparison of Sub-Genre's Title Sequences

Here are the orders and timing for the credits of two teen films - Kidulthood (Youth Drama) and Mean Girls (High School Drama):

There aren't any similarities in these two films' opening titles which means, however, that there are many differences.

While the Mean Girls titles are spread out with gaps in between them, the Kidulthood titles are shown at the beginning of the film and are very brief. Also, there is the bare minimum shown in Kidulthood whereas, in Mean Girls, we see a lot more. This is because Mean Girls had a much higher budget and therefore more people were involved in the film and would need to be credited. In Kidulthood, however, there are a few production companies - this is because it is an independent film and therefore had more production contributors as opposed to individual contributors.
