It's kind of a tough call. Koei's "Warriors" series of games are some of the most polarizing around. If you enjoy ridiculously over the top hack n' slash action, then I would highly recommend. However if you get bored of that kind of gameplay easily, then you'll probably get burned out pretty quick. All in all, Hyrule Warriors is in my mind one of Koei's most well done Warriors games, so again, if you don't find the gameplay overly repetitive, then the game is an absolute blast.
(Quick shameless plug for Dynasty Warriors 8 and Warriors Orochi 3, two of the BEST Warriors games. Seriously for anyone who enjoys HW but hasn't played any of Koei's main series, check these two out, I doubt you'll be disappointed. I mean WO3 has the biggest cast of playable characters in ANY game at a whopping 145 CHARACTERS in the Ultimate version)
