OK, so i've binged the whole season, concluded with season's finale, today's episode 9.
Overall, it was an enjoyable watch. The two main things that bothered me the most were:
1. The non-existent range of emotional facial expressions the actress that played Ellie had
2. So much screen time stolen from Joel and Ellie's story by overcomplicating and prolonging the side stories (flashbacks)
I did not mind little changes here and there, nor even completely new scenes (i.e. ellie's birth), what bothered me a bit was leaving some details out, for which i could not find a good reason, and which could bring more depth to the main protagonists, instead of prolonging the aforementioned flashbacks.
How is it hebephilia when Riley is just 16? Both girls are merely teens.
