Honestly, I...well...I don't know where to start on this Flash. I guess I'll start with my personal opinion- this is a very bad movie that should be removed. But of course, you can't just be a dick in reviews, you need constructive criticism.
I think the idea of, "Eyebrow Appreciation Day," is unique, but it's also one of those gray areas where it could be funny but if you screw it up it sucks. I'm giving you the best advice I can here: remove this from the portal, and work on it. Don't just try to extend it to throw in more jokes- just get the material you want in it, in it. If you try to make it something you don't want it to be, it ruins it. Put some things that you think are generally funny, sometimes it can screw up a Flash to try and make what everyone wants. Everything doesn't just start out wanted- people notice it, learn about it, then they want it.
With that all said and done, I'm gonna say that this is NOT a bad Flash, it is just an unfinished one.
