>>20098833The official channel has subbed clips and a subbed variety show (Wachastars). Their 3D debuts or full-member collabs are good places to start. If there are any members you're drawn to more than others try catching them live or browse their VODs. If you like singing check out their covers. There's a whole playlist for them on the official channel.
I also highly recommend watching their first live.

>>20100248 put it well. Also call me sappy but I love idols and to me they're shining idols.
