First, I must say that I watched it through. As such I at least gave it a 7. I never watch anything through if it's not at least a 7.
Overall I liked the show, but after I finished I felt it could be so much more. For the good parts, the acting is overall good, specially from Ms. Alba. She's really expressive and charming, but for me her dialogues were too cheesy and teen "angsty". Teen "angstyness" is something really prevalent in today's shows, specially on Netflix, as the target audience is mostly teenagers and twenty somethings. Yeah there was an evolution in the characters attitude through the episodes but not that much. Too much drama and teen conflicts and too little action and fighting on her part. I hope in second season she gets the chance to to more. The overall plot is interesting enough, but it only started showing what it's about in the last episode. This season had serious pacing problems. Too much time spent with teen drama and romance, and too little in the actual plot. The show is called Warrior Nun for a reason. Several dialogues had me cringing. The teeny rebellious jokes were overused. So those were the things that harmed the experience for me, pacing, bad dialogues, specially for the main character and the over focus on teen drama. That said I was left wanting to see more in the second season, so here am I hoping for things to get better.
