The story of Big Windup is for the most part entertaining. I was glad that they made the whole game that they were playing entertaining, and not just the 9th inning. However there were times when the story seemed to get repetitive, and the story itself moved at an incredibly slow pace. Despite the plot being entertaining, I found it to be nothing special. There was little in the way of depth to the story either. Despite this there where times when I laughed, and times where I really felt the moment that was being presented to me. Overall, the story is entertaining, but it is a bit thin and it moves at a snails pace.
The animation was mediocre at best. There were several instances when they used still frames of the characters. Also there was one moment that took me off guard where all they show is a still frame of the crowd cheering the team on. The style bothered me a little bit with the shape of the mouths, and it looked freaky to me. Mihashi looked especially freaky and it was almost like they werent humans.
There are really only two characters that really make them important. Mihashi to me was a complete wuss, completely insecure, and he trusts Abe too much. He really seems to be a flat, one dimensional character. Abe was entirely too mean. This left me with the impression that he was just a jerk to Mihashi and he has anger issues. He also seemed flat to me. The only member of the coaching staff that gets any amount of time is the head coach, who i found to be very wise. I felt like they should have spent more time on the rest of Mihashi's team. However Big Windup has a remerkable cast of minor players, which is far more expansive and interesting than the main characters.
The story was ok, but nothing that made it stand out. The animation is lacklusterm and looked kind of freaky. The characters where for the most part, flat and one dimensional. Big Windup is not a good anime, but it is not a horrible one either. Its a mediocre anime, and with mediocre animes, there are much better ones out there.
