I just hope it leads to some major changes in the episodes to come and not like we're back to a previous level yet again.
Also, it didn't feel like a proper closure not with a Rick walking out of the closed doors of the chamber. What happened there that we didn't see.
Anyway, two of the major plotlines were mashed together and ended up in a scene without a visible cliffhanger. A chance to search for a new driver for the series maybe.
I wish this episode was a proper movie, and I didn't have to carry through it the excitement and sadness all at the same time. I mean the movie would be nice, but probably it would be too hard to switch to different gears, probably it wouldn't work. Who knows, but it certainly wouldn't hurt to take the resources used on unimportant episodes and transfer them on a movie.
