User blog comment:Percivalxx/Which series of Merlin did you find the best?/@comment-4650675-20130103115630

My favorite season of all time is season 3! The first time with a villain within Camelot was exciting, we had many new adventures (The Castle of Fyrien, The Eye of the Phoenix), new creatures (Fisher King, Grettir, Wyverns, the return of the Sidge) new places (The Crystal Cave, The Perilous Lands) and overall I simply loved almost everything about it. And let's not forget the epic finale, the return of Freya and her becoming the Lady of the Lake and so many more.

I think series 1 would follow, then series 4, then series 5 and then series 2 (due to the many filler episodes)!
