It’s time for another episode offfffff…teenagers make you feel super f’n old!

With it now officially being Back to the Future Day—the day that Doc and Marty travel to in Back to the Future Part II—the Fine Brothers Entertainment YouTube channel was sure to capitalize on the big day with one of their “React” videos, with teens reacting to the future the 1989 sequel envisioned and how different it is from the day we’re living in right this very moment.

Click on over to the other side now to watch the Teens React to Back to the Future II video now.

People love watching other people react to things, whether it be scenes from a movie or TV show, video games, some form of technology, and so on. Reaction videos are used to market upcoming horror and comedy movies to people who haven’t seen them yet, and to make those who have seen them laugh.

The React videos from Fine Brothers Entertainment have smartly built a collection of videos on this undeniable fascination with reactions, having people of all ages react to all kinds of things, usually from a different generation to ensure boggled minds. These videos can often make you feel so very old, and that’s quite depressing, but we still watch because they also deliver on the nostalgia, which makes you feel all warm and fuzzy inside! Who doesn’t love testing one’s own emotional stability via a brief viral video every now and then?

The latest videos tackle a big one: Nintendo. Teens, including Game of Thrones star Maisie Williams (who recently did a Saved by the Bell reaction video), react to the Nintendo console itself and then to hit games Super Mario Bros. and Mike Tyson’s Punch Out!! You can watch the videos below.

Game Of Thrones star Maisie Williams made an appearance on the Web series Teens React for an episode featuring the 1990’s hit TV show Saved By The Bell.

In this episode, the 17-year-old actress and several other teenagers watch clips from Saved By The Bell and comment on everything from the theme song, the clothes, the hair, and the various relationships between the characters, as well as some of the more memorable scenes from show, like Jessie’s caffeine pill addiction. They also assess how the storylines and scenarios for the series, which celebrates its 25th anniversary this year, would go over with today’s audiences. They even take a vote for bigger hunk – Zack or Slater?
