The choice of story structure in A3! is bizarre. The time spent on the seasonal troupes is evenly divided, so you get six episodes with each of them. The show starts off with recruiting mostly theater newbies and watching them learn how to act. Then, six episodes later, the show throws them to the side to focus on finding five new guys, who you watch learn how to act, get tossed aside, and repeat. And repeat is the keyword. The whole show is just watching some bumbling idiots learn how to act four times in row. Most of the characters don't get enough screentime to differentiate themselves from the cast of 20 boys, so instead they have to fall back on one-trick pony gimmicks to have any memorability. There's occasionally some decent drama, though nothing unique, and most episodes end up quite boring.
The second cour is at least marginally better than the first. You have a solid character dynamic between two boys in the Autumn troupe who start out hating each other but end up forming some grudging respect for each other. The Winter troupe is where the show decides to introduce some supernatural elements for the first time 19 episodes in, including getting the boys stuck in a literal time loop. It's too little too late to really recommend, but hey, if you've made it this far, you might as well finish it out.
