My most favorite episode of this season are the one with the snakes ,the other one with the vat of acid and the premier . Each time a new episode airs I am hoping it's a good crazy emotional sci fi one as I used to from the previous seasons ,but unfortunately I am not getting what I hope . So what's the problem with season 4 . I think it is the new writing stuff . The new writers with no doute aren't engaged deeply with the complicated structure of R&M and what audiences predicting from this unique masterpiece that the creators had etablisled its baces . In conclusion I am hope the season finale to be a mind-blowing one and that the creators learn from their mistakes in this season to make season 5 dope and my advice to'em to get the old writers back to make R&M great again. Stay safe
