I found this episode quite enjoyable. There was a good mix of serious and humorous moments throughout.
The bromance scenes between Arthur and Merlin during the first parts are great, and then watching an enchanted Merlin try to kill Arthur was highly amusing, myhusband and son were in stitches lol! We were happy to see Morgana finally come face to face with 'Emrys' and to see a small battle between the two.
Altogether it ranks up there with some of my favorite episodes, and is a great watch for the whole family.
