It's the annual collegiate football game between the cats and the mice and the auctorial voice is on the mice's side in this 1941 edition of the oft-repeated Terrytoon.
While the football game may have been annual, Paul Terry's studio actually repeated the theme every two or three years, at least since its founding in 1930. They did this with several of their stories. While there is nothing wrong with this -- all murder mysteries begin with a murder and even in this day and age, a lot of romances have boys meeting girls -- there should be something different to justify the latest iteration.
Also some of the gags change and there are certainly technical advances that make the cartoons better. In 1930, Philip Scheib's score was the only sound effect and that was synchronized to the gag. Now it supports the mood and is well integrated into dialogue and sound effects. The character design and background art are richer and have some beauty to add to their utility. Motion is far more fluid and the gags are executed better.
Those, however, are technical details and in these reviews I try to look at the movies not only in terms of absolutes, but in terms of what was available or common at the time. We may not think much of the ancient Egyptians for building pyramids, but we don't fault them for not having cel phones. In like wise, I don't fault a Terrytoon from 1930 for not having the sort of art that this one has, nor this one for not being in Technicolor. Such things might have been technically possible -- Disney had excellent details in 1930 and some Terrytoons had been in color for a couple of years at this point -- but there were limits to Terry's budgets.
Still, there is no reason to praise someone for doing an old story in an average way. That's what this one is. I'm sure I'll see the Terrytoon from 1943 or so with exactly the same story, some new gags and some old ones; that will be in Technicolor, no doubt, and I'll feel the same way about that: decent but not exceptional.
