The 2022 year in review has been refreshed, and the stats look much better. Although drama count is correct once you take out specials, movies are still 3 short. The last 3 movies I watched, all on Dec 31, weren't counted, since one of the main leads in it should have put him in the most watched list with 4 titles, and the rating I gave the last movie should have put it in the top movies list.
Looks like specials and ongoing dramas don't count towards actors/actresses watch tally. I was expecting certain actors to appear in the list, but didn't. Two actors who showed up in the original year review with 4 titles each are no longer in the list. Confusing since, I'd watched 3 movies +1 drama of one, and 4 dramas (1 ongoing) of the other, and yet there are actors with 3 titles that have replaced them on the list.
