A surprisingly good comedy fantasy anime with good worldbuilding, humor, and characters that goes to show that you can have a show centered on sex yet have great writing.
K-On!
KyoAni breathes their signature love into this piece, making it another great show for de-stressing and having a stakes-free good time.
Girls und Panzer: der Film
While it's literally the same plot as the series, the action and animation are improved (though some action is as believable as a Fast and Furious movie). It has a vibe of watching an eSports match, just with very Moe anime girls.
Yakitate!! Japan
Yakitate!! Japan is a goofy, wholesome comedy that channels a similar vibe to the great Abridges series of the early 2010s with quality humor and the cast doesn't really take the show seriously.
Wotakoi: Love is Hard for Otaku
Wotakoi hilariously and truthfully shows the joys of being passionate about what you love and finding someone with that same passion, and the difficulties when your passions don’t match. It shows the unique difficulties of working with certain personality types that are more common among nerds, and how that dynamic is different for different couples.
Gabriel Dropout
A good short, dumb, weeby comedy worth your time. Good for when you don't feel like investing much in what you're watching.
Rascal Does Not Dream of a Dreaming Girl
An amazingly emotional and excellent cap to the loose ends left by the main series, this movie is everything good about the series but better.
Rascal Does Not Dream of Bunny Girl Senpai
Take the philosophical and supernatural side of Monogatari and mix it with the truthful teenager experience of Toradora, and you get Bunny Girl Senpai. Which actually has nothing to do with Bunny Girls, despite the title.
Konosuba! The Legend of Crimson
The Konosuba Movie is the series at its absolute best. From start to finish, the comedy is perfectly on point.
Re:Zero – Memory Snow
For an OVA this is surprisingly well done...a good, funny time worth watching if you liked Re:Zero. Plus, there's a Konosuba Easter Egg!
