Anime fans tasked with setting out the conditions for making a hit anime have provided a disturbingly likely list of candidate elements any modern hit is probably going to have to include…
The most highly regarded conditions for becoming a hit anime:
1. Don’t rape the original!
2. Make the art cute
3. Have a sweet OP
4. Get a cast of top seiyuu
5. Show some cool battle scenes
6. Include some unexpected twists
7. Have a sweet ED
8. Include ero in moderation
9. Use lots of moe elements
10. Fill it with lots of cute girls
Type A fans seem unlikely to be well served by this selection, but a quick comparison of the list to actual hits (notably K-ON! and Bakemonogatari, both top sellers) seems to suggest following its guidance is a sure recipe for a hit.
