I really can't believe how the show and my opinion on almost all the characters changed the last few weeks.
Ward was an okay character but I really disliked him. He had like every cliche for a weapon and combat specialist and it was bound to be Skye's love interest... And then betrayal. The villain Ward was the best Ward. Ruthless but still he has his weaknesses. Even to the very end, when he confronted Skye he just could not attack her but tried to exploit her weakness about him.
Skye also surprised me. I didn't like her at all first and it was like she was only here because the team needed a beautiful girl(no offense to Simmons). The fact they passed her as a master hacker was also kind of annoying. As her character started to develop and she stopped being suspicious but a part of the team, she became my favorite. She's funny and I liked almost every scene with her after Quinn shoot her. And her scenes with the traitor Ward is just gold. Probably my favorites from the series.
About Fitzsimmons, I liked them and I still do but their relationship annoyed me a lot, especially after Trip's appearance. They were a great science duo but the writers just didn't want them to be a couple. And after Fitz started to show his affection about Simmons, Trip appeared and then she pretty much friend zoned him at every single instance. Even at the very end... I'm afraid Fitz will be disabled at season 2, either on wheelchair or even completely but I hope this doesn't put him out of the show or degrades his character.
Son of Coul is just awesome. After watching the first few MCU movies, I really did not remembered him. Avengers finally managed to make it clear to me who Coulson was. Despite that, his "death" seem unimportant. Just a plot device. When I started the show, he was just the guy connecting the movies and the show. Nothing more, nothing less. His revival was a bit intriguing, but I didn't expect much. It was much later, after his struggles with the alien, Hydra and Ward's betrayal that I actually enjoyed his character. In the last 3 or 4 episodes. Now, I really don't want him to go mad...
I still hate May though and Trip is just a Good Ward clone and pretty much non-existent. I want to see more from both of them. May was suspicious and cold for more than half the first season and even if she died, nobody would care. I hoped for more interaction with her mother, I wanted to see her soft side but this didn't happen. And Trip just needs more focus. He isn't bad, just really bland.
