The main complaint: Netflix's decision to "split" the season in half. The first 4 episodes dropped on August 6th, but viewers will have to wait until September 3rd for the second half. This breaks from the streaming service's usual practice of releasing all episodes at once.
Fans aren't hiding their disappointment – after three years of waiting, they're being asked to wait again, even if it's just one more month. But when you've got a great story (and Wednesday's second season definitely delivers), you want to binge it all at once.
Many viewers also didn't like the changes to werewolf Enid Sinclair's ( Emma Myers ) character and her dynamic with Wednesday ( Jenna Ortega ).

What Critics and Viewers Are Saying
Critics rated the new season higher than the previous one. On Rotten Tomatoes, season two sits at 83% compared to season one's 73% – solid growth.Reviewers praise the "more structured and, frankly, more interesting story," noting the "compelling mystery, dark sense of humor, and stellar cast" along with Tim Burton's signature aesthetic.

It's not all doom and gloom though. Based on comments from the show's dedicated subreddit, many fans are loving season two:
Wednesday's second season finds itself in a weird spot. It's getting praise, ratings are climbing, but viewers are angry – not about quality, but about delivery. Netflix is playing the long game, stretching out the pleasure (or trying to make people pay for another month of subscription), but fans would rather enjoy the whole story at once.Reddit user CriticallyHonestNerdOverall, this season is much more interesting than the first. The other family members are finally involved in the plot. Gomez is much more likable than in the first season, and Pugsley is a cool character.
For now, Netflix is winning – everyone took the bait, they're discussing the show, waiting for more, building theories. But the question remains: is quality content worth these marketing games? September will show whether fans forgive Netflix for this drawn-out intrigue or completely hate the "divide and conquer" strategy.
