I see from one of the charts that the average movie rating from 2019 is over .5 higher than the previous 5 years, in what appears to be a big jump. Is it possible that recency bias is only relevant on a shorter timescale? It looks like ratings are higher for movies that are a few months old, based on the data. I wonder if this is generally true, or if early 2019 happens to have higher rated movies.
Sure - for example, fans of a particular actor, director, or series are more likely to go see a movie soon after release in theaters as opposed to later via rental or streaming.
Fans are likely to rate higher than the general public, so over the first, lets say, 3-12 months, ratings often trend down.
Fake reviews and ratings must be a factor. For big movie releases it is hard to find IMDB reviews that seem genuine. I assume good portion of the ratings are fake as well.

It must have an effect given how common it is.
