Series Review

Monster is a true crime series that tells a new real-life case each season.

It is intense, emotional and often very uncomfortable to watch.

The show focuses on famous criminals but also shines a light on the victims and the mistakes made by police and society.

Season 1 – Dahmer

Evan Peters gives a strong performance.

The season shows how Jeffrey Dahmer was able to keep hurting people because warnings were ignored. It’s powerful but very graphic.

Season 2 – Menendez

This season covers the Menendez brothers’ case.

It shows family issues, media attention and courtroom drama. It’s dramatic and emotional but sometimes feels a bit uneven.

Season 3 – Ed Gein

Charlie Hunnam plays the killer.

The season is dark and carefully filmed but may feel too disturbing for some viewers.

Overall, Monster is well-acted and gripping, but not easy to watch.

It’s best for viewers interested in serious true crime stories.
