After the episode with the return of Uther, the 4th episode of Merlin series 5 does less good with the reviews.
“Another’s Sorrow has a slow and, when you think about it, nonsensical plot, but it does have some great performances and heart-pounding fight scenes that almost makes up for its shortcomings. Not the strongest episode, but certainly not a waste of 40 minutes.”
States the review of Trollish Delver. In my own personal opinion the episode was all right but had indeed a slow pace.
