2ShotsOfGeek.com has posted a review of Robotech: Love Live Alive and here is an excerpt.
Everything is just spot on. The new soundtracks while familiar add a layer of freshness that builds the atmosphere. The Voice acting and the return of the narrator were near perfect. The animation felt natural and blended the new and old quite well, with only a few transitions that felt too sudden. In one concert scene towards the end, we get some strobe effects that are a tad bit too intense. While it fits the scene, it could pose an issue for someone sensitive to seizures. The second half of the film was the strong point, still a very enjoyable film from start to finish.
