This is probably the hundredth post complaining about the show's finale but I don't know where else to put my frustrations.
Dean deserved better. I don't care how symbolic the ending was, but after all that trauma, we as fans and the characters deserve a happy ending. I genuinely don't see the point of killing Dean and Cas like that. And Ik they writers just wanted Dean to be "straight" so he just never mentions Cas at all after his death. Like not even mourn him (or at least show the audience that). He mentions him twice and the plot continues. Dean literally lost hope when Castiel died in S13. (The writers betrayed his character)
I started this show because of Destiel and I eventually obsessed over Sam, so I love all three of the characters and the way the last season and the conflict ended just feels so unsatisfying. I know Covid restricted a lot of the plot writing, but they still could have done so much better.
Also, Sam did not get a "happy ending" and it was a huge betrayal of his character arc. His whole journey has been about him accepting the hunter's life and also somewhat liking it and he even becomes a leader in S12 and S14 (he also gets into witchcraft and is good at it). He had to live without Dean after everything they went through, after only depending on each other, fighting against The God and believing in each other only, he had to live alone. I know he wanted a peaceful life but after S8 it was made clear that he could never really have a normal life. And what happened to Eilleen? I know Covid caused a lot of shooting issues but at least they could have had one conversation about what happened to their relationship. They could have been a cool hunter couple and it was just forgotten by the end. His "normal" life is very difficult to accept and it feels like he is just speedrunning to die and meet Dean in heaven.
The fact that the brothers had to be separated by death and not mutual understanding pisses me off. I really wanted Sam and Dean to go their separate ways (like not entirely separate, ifykwim) and live the life they wanted, and occasionally hunt together (because they are finally free and they can be who they want to be and Chuck is not making them face each other or the world ). Castiel could have been brought back by Jack but the writers' h*mophobia (or shall I say the fear of the fans who don't like the queer pairing) didn't give us the reunion we deserved of Cas and Dean. (Even if we consider that Dean and Cas are not romantically involved, they still deserved to be together because Castiel was the only other character that stayed so long that he is family)
Honestly, the only character that actually represents Free Will is Castiel, even though he died after confessing, he did the one thing no other character could.
(Oh my Chuck guys, just because I started the show because of Destiel, doesn't mean that I am being dumb and lack media literacy. This is just my opinion and I just wanted them to have a good happy ending, like a life they could have enjoyed instead of only being happy in Heaven. Yes Castiel is bought back but we don't see Cas and Dean at least meet each other in heaven. I am not saying that Destial had to be canon, at least it should have been a bit more happy ending than the bittersweet ending we got)
