First off, let me say that you can watch "Warlock: The Armageddon" without having seen the first "Warlock" movie. Of course you will have more depth to the warlock character, if you have seen it, but you will not miss out on anything if you haven't.
This sequel is as good as the first movie in the series.
Again, the role of the sinister warlock is portrayed by the charismatic Julian Sands. And in this movie the character is much more dark and evil, far more twisted than the warlock portrayed in the first movie. Julian Sands is so perfect for the role of the warlock.
The cast is good, and the roles of the druids are good, both for the young druids and the elderly druids.
The movie has a bunch of cool effects and wicked magics, something that have to be seen. However, it is not all good though, the scene with the knife went horribly wrong. That knife is perhaps the worst CGI effect I have seen to date.
For fans of adventure genres or for people who like to play D&D games, this movie provides good entertainment. And like the first "Warlock" movie, this also have enough entertainment for more than one watching. I never grow tired of it, at least!
