This is a nice addition to the P★LEAGUE Series. 1 - 2 - 3 and now 4! :) The battles between the girls (solo and team) were fun to watch and I appreciated the neat camera work capturing the action and expressions from different angles. The table discussion at the end was fun, too, despite the language barrier.
I think foreign viewers, like myself, may only enjoy it if they have an appreciation for the sport of world bowling (especially Japanese women bowling), like playing bowling themselves, and like to support them. I'm a recreational bowler myself, have enjoyed it since I was 6, and like seeing the bowling scene in Japan growing once again.
