First season starts with a bang when one kid- Will Byers, goes missing and this is followed by more people disappearing and appearance of a mysterious girl. While searching for Will his family and friends get to know about some experiments and an alternate reality upside down which is threatening their existence. It also sets up the character of Eleven, where it was shown how and what powers she develops. Major part of first season is about character development and the characters trying to unravel the mystery behind disappearances.

Second season is about the creatures from upside down hitting back and unraveling past of mysterious girl- Eleven and development of new chemistry between Police chief Jim Hopper and Eleven. They could have easily avoided episode 7 where Eleven meets her sister Kali who possess power to make people see or not see something unless , she has some Important role in upcoming seasons, It hampered the momentum built in episode 5 and 6 which continued in episode 8 and 9.

My favorite scenes from season 1 => When Mike's younger sister sees the creature from upside down => The way Lucas get into commando mode to get back his friend Will => Fight between Will's Brother- Jonathon and Steve

My favorite scenes/episodes from Season 2 => Chapter 5 Dig Dug where Jim Hopper get stuck in alternate reality is the best episode of both the seasons - It gave me Goosebumps => When the creature hits back i.e. episode 6 and episode 8

The group of Kids - Will Byers, Dustin , Mike and Lucas are shown as nerds and do very well especially Dustin who on first look appeared disgusting but as the story goes on he is one of the cutest and funniest character and not as bad as i found him on 1st look. Will didnt have much to do in Season 1 but in season 2 he is pretty good as someone being taken over by creature or virus. Mike is the one i found least interesting but he is shown as someone who is always there for his friends. Lucas is fun throughout but best part is in second season - his chemistry and love spark with the new girl who enters their group - Maxi and his banter with younger sister. Maxi is shown to be asocial and recluse due to her broken family and abusive step brother but once she spends some time with Lucas and Dustin , she endures even ill-treatment by Mike just to be the part of their group. She is the coolest in their group.

Jonathon - Brother of Will Byers, plays a weirdo , freak who love photography and loves his mother and brother a lot and is shown to be very responsible family guy.He is head over heals in love with Nancy but not expressive Nancy Wheeler- Sister of Mike, is studious, super intelligent but for a period tries to be a rebellion to be part of group of Steve when she starts dating him , but soon she finds herself more inclined towards Jonathon. She is shown to be courageous and brave. Steve - plays boyfriend of Nancy - a popular rich boy who has slept with many girls , initially though even Nancy looked like one of them but slowly it was shown that despite his insecurities regarading her,he cares about Nancy and even fight the creature and as the character develop he is shown as a guy with a good heart , One thing i didnt like is, though he was the most popular guy but is beaten black and blue by every guy( i liked him being beaten by Jonathon but not the other two) Bob - Boyfriend of Will's mother- Joyce, is very intelligent and sharp , though seem little boring with his outdated jokes and over friendly nature but his love towards Joyce and his endeavor to get the trust of Joyce's son was endearing. He plays an important role solving the figures drawn by Will to save Hopper from creature and then ended up being "Bob-The-Superhero" when he protects all of them stuck in Hawkins lab full of Demagorgans

To connect to a series most important things is to connect to its characters and the characters i connected to most are Eleven- Mysterious girl, Joyce - Will & Jonathon's mother and Jim Hopper

Eleven - she was called weird in 1st season but i had a crush on her the first time i saw her and i have fallen in love with her , this much cute i find her. She is shown to be brought as guinea pig away from real world , so her interaction with the real world was interesting , she learns about friendship , family , home and all i can say is the actress Millie Bobby Brown has enacted her part with aplomb. Only thing i didnt like is she shown to be in love with Mike and iam super jealous

Jim Hopper - He plays Hawkins police chief who has lost his daughter to cancer and wife and stays alone but he cares about his town , small kids and his friend- Joyce . Despite showing him as indifferent, hard and a cool guy he has a very soft heart- the reason he develops a father daughter relation with Eleven and does everything possible to keep kids safe.

Mother of Will and Jonathon - Joyce - played by Winona Ryder is a caring mother though she isnt able to devote much time to her children due to her being working single mother . Winona has given a superlative performance especially in season 1 . She deserve every award for her performance as brave , determined courageous mother who is nervous and paranoid but will do anything to get her son back. Her smile is also very infectious

there are few other character in small roles like Brenner , Kali, Billy , Owens, Karen but there is not much to discuss about them till now
