You definitely should - Hexen has a great atmosphere and a lot of improvements to the Doom engine (hubs, scripted events, fog, earthquakes and more).

Hexen II is pretty good too, I have played it for many years and never got tired of it. Gameplay is just like Quake, but less linear and requires more thinking. There are lots of puzzles to solve and some of them are very difficult. New features to the Quake engine include objects you can read (like books, letters or signs on the walls) that give you clues or background story information, hundreds of destructible objects (furniture, statues, plants, windows, doors, etc.) and 4 different classes to play with.

So yeah, I definitely recommend the Hexen series.

I should also mention Heretic - the predecessor of Hexen. It is very similar to Doom but has a few unique features of its own (inventory, alternate weapon modes, etc.). It's worth a try :)
