If you want a hyper-compressed version of everything that has happened up to episode 11 while listening to Futari roast the hell out of her sister, then sure, watch this. There's no real reason not to. The only issue that I have is that it is stupidly difficult to find a place to watch this on. Like seriously none of the major streaming services have this. Honestly though, this is just a filler episode that's only good if you want to 100% BTR, if you want a real recap of the series just watch the movies. They have way more content, original scenes, and areoverall just a better summary.
