What I liked about the series:
(+) Above average animation quality. Colours were bright and vibrant.
(+) Mech fights were decent. They were spaced out because a good chunk of the anime involved duels between Bubuki (weapon) users instead of the larger-scale Buranki (mech) brawls.
(+) There are trains.
What I disliked:
(-) The story took a backseat for most of the early episodes, with only vague references to this and that. Basic plot details were only revealed on the 11th or 12th hour. Up till them, the anime seemed like a hollow setting for the sake of the fights.
(-) The main squad was rather boring. Like the average shounen title, they spent half the time bickering amongst each other instead of doing what they're supposed to do, and the other half surviving battles either with plot armour or because their enemies for some reason refused to finish them off. With the huge plot detail dump near the end, the Reoko squad seemed way cooler in comparison. The anime would have been more interesting from their perspective instead.
TLDR good for the big fights with little else.
