Zero no Tsukaima Final: First Impressions

Saito is summoned from regular Japan to a magic world by Louise as her familiar. Through many trials and tribulations, they grow into a powerful warrior/mage duo and develop a complicated on/off/love/hate relationship. This is the fourth and final(?) season of this series and looks to close it out.

First Impression: I've always had a positive outlook for this series, but I don't know if I can take a fourth season, especially after a 3 year break. It has a very 'Slayers' fantasy feel to it, only without a smart-aleck lead, replaced with harem themes and very irritable main characters. I will watch because I've watched the previous three seasons, but on its own, I feel like it's not interesting enough to attract newcomers.
