As I do, I've stolen this list from DisposableMiffy but you should also check out Michael's and Darren's lists cos they're good people and have also seen way more franchises than I have, so their lists are better than mine.

I also stole the formula used to calculate the percentages from Darren (thanks again mate!) so I will copy and paste his explanation cos it's way outta my skill level...

"score = (200/9) x (average minus 0.5)

This converts my average to a percentage where 0% would be a franchise where every film is rated 0.5 stars and 100% goes to a franchise where every film is rated 5 stars.

The notes list the franchises, their scores, and all their films.

How these are ranked:
1. By score (highest first)
2. By number of films (highest first)
3. By quality of their best film (best first)

This list clearly doesn't reflect my actual franchise preferences and proves that often my ratings produce results which don't reflect my tastes; nonetheless it is a useful guide to the franchises / films I like."

My rule for inclusion is that each franchise must have at least 4 entries and that I must have watched at least 4 of those.
