Okay, I have had to think on this for a bit, because there was one thing that truly bothered me.
The way that Dean died. I was mad. Furiously mad. He's been shot, stabbed, turned into a vampire, tortured in hell, was in Purgatory for a year... and he gets killed by a nail in the wall?
Then it hit me... he went out exactly like he thought he would. On a hunt, saving people. And that's exactly what happened. They removed all the major threats, so only basic level monsters are left. Eventually, their luck would run out. And that DOES make it more believable. I'm reminded of how Lt. Yar died on TNG. It seemed quick and empty, but she died doing exactly what she was trained for... and her line of work is the most dangerous in Starfleet. That made sense with her, and it made sense here.
I was crying. A LOT of single man tears during this. Dean's goodbye scene to Sam... waterworks, man. Waterworks.
And it didn't stop there. I was so thrilled to see Bobby again, sprung from Heaven's jail. I've always had a soft spot for him. And hearing Castiel was brought back was great to hear. More tears there.
And I like what they did with Heaven... it's truly a place where everyone there can be together. I was hoping to see Mary and John there, but the pandemic was the likely culprit for their absence. Jack did real good, though, remaking it like that.
And Sam shutting down the Bunker for good... that was their home for half of the show's life. Sad to see it gone.
I like the montage of Sam and his son, Dean. All during "Carry On Wayward Son". (Which at first, I was confused why it wasn't used during 'THE ROAD SO FAR'. At least it was used, and a good chunk of the song, too.)
Bobby's explanation of time being different there is exactly what Dean said about his time in hell. In that case, 40 years went by in those 4 Earth months. It seems the reverse happens in heaven, given what we saw, and it makes sense if you think about it. We always say "time flies when you're having fun." And when bad things happen, it feels like a LOT longer than it really is. So that was a nice bit of symmetry.
The boys got to be reunited in heaven. It's a good reward for all they went through. They more than deserved it.
My only real problem was that Dean died so very soon after their ultimate victory. They couldn't enjoy it for a couple years at least before his death? No matter how I try, I still cannot get past that.
With a show that has been on this long, and a fanbase as rabid as this, you are NOT going to get an ending that will please everyone. The best you can hope for is something that serves the characters right, and I think this finale did. It kept true to what we've seen before.
My biggest sadness is that we'll never get a reunion movie or special. This was a FINAL finale. But after 15 years, I can understand the guys wanting to hang their hunting shirts up for good.
A last thought...
This show has become such a huge part of me. The amount of joy and fun I've had watching all these episodes all these years... really, 1/3 of my life... is incalculable. It was one hell of a ride, and I will truly miss it. No new episodes, but I have all the dvds, so I can catch them anytime I feel like I need to hop into Baby.
Thank you, SUPERNATURAL, for those endless moments of drama, escapism, thrills, action, comedy, fun... and most of all, a beautiful reminder of what matters most. Family.
Carry on, my wayward son...
