Spoiler alert, i guess, because there wasnt anything we didnt already know.
I didn't have high hopes for this prequel. But what i definitely didn't expect, was for the first episode to just be the flashbacks from the OG dexter in chronological order with different actors. It only covered the storyline with some frufru inbetween. Harry getting sick and the nurse trying to kill him Dex killing the nurse that was his first kill that they already had in the flashbacks in the OG Dex. Only they made his first kill WAY more organized with better execution unlike they did in the OG Dex. The OG flashbacks were so much more believable to what his first time killing would be like.
