That wasn't really the end of Hydra. Garrett was simply using Hydra to carry on his own agenda. Hydra obviously goes much much deeper than Hydra.
Loved the back and forth between Coulson and Fury, especially during Garrett's spiel. They have some good chemistry together. Was the gun that Fury gave Coulson the same one that Coulson was using when he challenged Loki?
And that May vs. Ward fight was awesome. Having power tools at your disposal always makes things fun!
