Critic reviews for Monster

I like this. I like this as much as I like the idea that Gladiator is called Sweaty Men on Earth-19, and as much as I like Iris on the ground during a monster attack, trying to help in a very practical way.

The Flash went from luke warm shower last week to a straight up tundra ice bath episode this week.

This week's Flash didn't offer much in terms of action, spectacle or a compelling villain. But it did deliver plenty of great character interaction.

The plot works rather well, giving Caitlin some interesting motivation for what could grow into a something of a villainous turn.

I can't deny that Cavanagh's turn as H.R. provided most of tonight's best moments.

I would totally be fine with the show killing off Julian or transferring him to some other city.
