'Westworld' season 2 has critics gushing and a 100% rating on Rotten Tomatoes

Critics love season two of "Westworld," with many saying it's even better than the first, which premiered in 2016 on HBO.

The second season currently has a 100% rating on Rotten Tomatoes and premieres its first episode on HBO Sunday.

The first season was a hit with critics and audiences, but it ended on a somewhat disappointing note because a lot of people predicted where all the storylines would end up.

But critics at outlets including Business Insider have given season two glowing reviews because it expertly expands the world into more parks than just Westworld, and increases the stakes for all of its characters, both human and host.

Here's what critics are saying about season two of "Westworld" (HBO made the season's first five episodes available to the press).
