Thank you Merlin.


This is a decent show...not really good but cheesy good. There are some parts that are fantastic and some parts that are subpar so it evens out to a decent show. Anthony Stewart Head as Uther is probably the best part of this show, he is a rock solid actor. This show had so much potential with having them the same age, they could have done SOOOO MUCH but they chose to ignore pretty much all of that potential. With that said, the series finale is INCREDIBLY AWFUL so it tainted the show for me so I would suggest just skip the last episode.


I agree with the other comments about the series finale. Skip it if you want to end the show on a good note. I LOVED this show because of the two leads. Not every episode was amazing, but there were real gems in there. They could have really done something different with the ending; it left me with a sour taste in my mouth... That said, I still recommend the rest of the series. It's one of my all-time favourites.


So painful to say goodbye. What an amazing series! Oh great. I'm crying again.


super amazing!


when i first started watching merlin i was just curious but now i cant wait till next season recommend this to anyone who would like to have another view at how king arthur became the man he was (in this tale ofcourse :) )


The weird thing about this show is that it is so awfully written, yet the humor is amazing.


@rottnkorpse .. I thought the whole series was pretty awesome, and I loved the way year by year it grew, as the characters grew! Everything about it was excellent! However, I don't agree about the last episode. Yes, I was disappointed, but only because I knew it was over! It was pretty much the way I would expect an incredible series like "Merlin" to end! I really wish it wasn't over!!


The early seasons were pretty great but it got progressively worse until I gave up, halfway through season 5. I hear I didn't miss much. Loved the dynamic between Arthur and Merlin though and am angry that they didn't do more with this show. If I had stopped at season 1 or 2 I would have probably given this an 8.


Series is decent but plots keep repeating. Everytime there's another infiltrator.
