Robin Hood is a great BBC show check it out :).
Do you mean the latest incarnation (now cancelled series) with Jonas Armstrong? That one was ok. Merlin is better though. Filmed in the same style as Robin Hood but better with a bigger budget. Plus, the Château de Pierrefonds is an excellent backdrop for Camelot, although I'm not too sure about the choice of special effects that depict the various so-called British landscapes with mountains as big as the Alps. Really?!! Cheesy but fun ;)
