“The Well” had been marketed as the tie-in episode with Marvel’s Thor: The Dark World and while it did feature a basic clean-up after the events of the movie, it didn’t really tie-in that much to anything from the movie.
That may be the only nitpick that can be found in this episode because if one would look at this as a S.H.I.E.L.D. episode, it actually accomplished a lot for the series as a whole for its characters, especially Agent Grant Ward.
The Asgardian Berserker staff was a plot device that worked more than people would actually realize. While “The Well” didn’t perhaps feature a cameo or two, it was in the end a more of an Asgardian case episode which did work pretty well.
