Season 4 poses on a fluent straight forward movement of the Stranger Things franchise, with a high action gory suspense with continuous story unfolding packed with high level of detail of characters, makes it a true watch till the end.. Criticism may come for the villain known as Vecna as it felt more like he was a more Of Talk- Then Show type villain yet Vecna"s origin story feels more deadly and satisfying and a lot of plot holes feel like they need to be covered for Season 5. Praise comes for the well written Storyline and plot, CGI and mostly giving an accurate dose of blood and action simultaneously to the different monsters and even by killing some some by characters ... Season 4 will be with no doubt the darkest season from all other 3 seasons, may the Duffer Brothers continue to make more shows like this.
