I did, however, seek out the title sequence on YouTube, which has a lot of weird images flying at the viewer through a kind of vortex:
The first time I watched it, I was like, "This all a bit The Tomorrow People."
Long before it was a one-season wonder on the CW, The Tomorrow People was a 1970s children science fiction show on ITV in Britain. It's arguably the worst television program that I've seen every episode of. (There are some things about myself I can't explain.) But the very best part of the show was the eerie opening titles, with a succession of images rushing at the viewer:
The most famous one is the big hand, which comes from a bit in the first episode, arguably the only good episode of the whole show. (Or maybe the title sequence inspired this moment, I don't know.) One of the Tomorrow People-- they're basically the X-Men, mutant teenagers with superpowers-- says to a new one who is coping with his new powers: "Imagine that your mind is a fist, a great big fist clenched tight. Now, let it open. Slowly. [...] Just think of the fist opening very slowly, like a flower." The opening hand is thus a central motif of the titles, representing the mind opening up to perceive the universe.
So when a giant hand flew up at me in the Class opening titles, I was like, "Aha, it is all a bit The Tomorrow People!"
Alas, the music for the Class titles, a song by British singer Alex Clare (Wikipedia says his genre is "Alternative rock / electronica / blue-eyed soul / drum and bass / dubstep / electro house / R&B soul") didn't work for me as well as Dudley Simpson's eerie theme for the original Tomorrow People.
So I decided to rectify this. I couldn't find a website that lets you play the music of one YouTube video over the images of another, and I'm too lazy to download a video, edit it, and re-upload it, so use this site: http://www.youtubemultiplier.com/5810bb0ca45bd-the-tomorrow-people-class.php
Your best bet is to quickly click the full-screen button on the video on the left, so you'll get just the Class imagery with the sound of The Tomorrow People. Someone on YouTube has done this, but they made an error in applying the Tomorrow People theme and it starts over halfway in.
Anyway, I like it. I dunno if it's better, but it made me smile.
