Depends what you want. If you want a static point and click, random turn-based combat RPG with a definite Deadelic feel, then consider it.
I, for one, would advise against it. The only thing that was a positive for me was the main quest (still predictable though). And maybe the writing behind two of your companions.
The rest - the turn based combat, side quest, cheap rewards, logic (or lack thereof) behind combat and leveling mechanics, bleak characters (aside from those two mentioned above), poor ending, painful lack of balance, absent immersion - is well, on the negative side of the game.
Huge disappointment for a game that was hyped as a great title. Play Divinity: Original Sin instead, or Jagged Alliance, or Shadowrun, or Expeditions Conquistadors. Save your money and don't buy Blackguards, you'll be doing yourself a favor. Unless you really intrigued by it, then do a thorough research before buying.
