Does anyone know where I can watch Merlin online? I want to refresh my memory a bit but can't seem to find a good website. Can anybody help me??

try this:
link

This is what I use:
link
you just click the episode, then 'quick play', then 'click to open in a new window', it's the best link I found and it doesn't ask you to sign up for anything

i find megavideo pretty good

You can watch it on the CBBC channel on weekends at around midday. You'll have missed quite a bit of the first series por now, though.
The CBBC channel is on Freeview channel 70.

i like this one :)

I amor this one;
link
It has all the episodes with different links
The link does not just have Merlin, it has all different kinds of shows.
One downside to it, is that it has a lot of ads.

my favorito for watching shows:
link

link is what I use. It's someone's blog but they have all of season 1, 2 and 3. She also has other blogs with episodes of Bones, Glee, Gossip Girl, True Blood, etc.

www.sidereel.com has links to all sorts of videos. Just type merlin in to the procurar bar and millions of links to episodes come up. But only do the megavideo ones because the others can potentially put viruses on your computer. Yes, from past experience.

Hulu has season 1 and 2 only. I can't find season 3 anywhere. Same with Netflex 1&2

If you have netflix you can watch it there otherwise you can use hulu. otherwise i get viruses when i use other sites

i know you can get it on netflix.
