For the last few years, I've thought about how most of the older "main series" Mario games are very different from each other, while the games in The New Super Mario Bros. series seem to be much more similar to one another (well I haven't played the most recent one), but now something else has hit me: In most of the older games, the average ending to a level would be different. In SMB, Mario would jump on a flagpole. SMB 2, you'd fight Birdos. SMB 3, you'd jump into that square thing in the black background. Super Mario World would have you cross that touchdown-line-thingy. Super Mario Land had Mario going into one of two doors/windows in a building. Can't really remember what the average level ending for Mario 64 was. But then for most Mario games in the past decade, The New Super Mario Bros. sereis and Mario 3D Land/World, Mario, Luigi, and friends go back to jumping on the flagpole. Why suddenly go back to that iconic ending and stick with it? So for the first New Super Mario Bros., it makes a little sense, since it's supposed to be like the older games (and I originally thought it was meant to be a straight-up modern 3D update to Super Mario Bros.), but then couldn't a New Super Mario Bros. game have its levels end like the levels in Mario 3?
In Back to the Future III, it's briefly shown that Buford Tannen had issues with Semus McFly, just like how Biff bullied George and Griff bullied Marty Jr. Yet we never see any scenes with them interacting (it was really there to be like the scenes in all the movies where Marty goes into a popular hang-out place in each year he visits only for a Tannen to enter yelling at a McFly, and for him to have ended up mistaking Marty for Seamus). So maybe it wasn't really needed, but it would have been good to see how Buford treated Seamus. Unlike George and Marty Jr, Seamus wasn't shown to be wimpy or cowardly, though he didn't seem to care about whether people viewed him as a coward. In fact we never meet any of Biff's children and never hear about Marty being bullied by a Tannen relative, but his brother Dave seems like the kind of person who might have been (during the original timeline, that is).
