Saiga is a normal high school student with a gift in mathematics. His daily routine is disrupted when his family gets news that his Father's remains have been discovered—a noted archeologist and researcher who had gone missing while exploring a site many years before. Among his remains were notes and artifacts that needed to be identified by the family near a notable triangular mountain in Japan known as "Japan's pyramid", a place suspected by some to be man-made. A meteor containing a strange robotic lifeform falls from the sky and begins to cause destruction, putting Saiga in danger and causing a mysterious bracelet from his father's research to activate and merge him with an ancient robot burried within the pyramid—a robot the runes describe as Reideen. It is now up to Saiga and guardian Reideen to fight against this unknown alien threat from the sky.

"Where there is life, there is conflict. And talking doesn't always solve everything" the "fairy" Maedasaki instructs the protagonist in his dream. "Reideen" is full of conflicts. Between aliens and humans, between giant alien "robots" and Reideen, between Reideen and the army, between the army and military intelligence, between departments of military intelligence itself... But the main conflict of "Reideen" is internal. This anime is in conflict with itself, unable to finally decide what it is and what it is about. As a result, it loses the battle to itself. Those mecha lovers who are attracted to action will find "Reideen" boring and overextended. Combats ...

Reideen is the epitome of a slow starter. Though it does find its footing a bit towards the end of its run, it's a show that requires patience in the early going, because the first 10 episodes or so are a real slog to get through.

One reason for that is the uninspired setup. If you've seen one "high school student is chosen by an ancient artifact to pilot a mech and defend Earth from an alien invasion" show, you've seen em all, and Reideen certainly does nothing to distinguish itself from that crowded field early on. Another factor is that the big mech action setpieces ...

Mixed Feelings
This one's quite the mixed bag. Serving as a modern telling of the 1970s super robot series Brave Raideen, this 2007 anime focuses on high school student Junki Saiga coming upon a powerful mecha called Raideen that he must control to protect Earth from a mysterious alien threat. As the alien threat escalates, Junki finds himself contemplating how to handle his role as Raideen's pilot while multiple factions seek to exploit the mecha's power or presence for their personal gain.

My reasons for finding Raideen to be a mixed bag come from the mixture of what it does right and wrong with its series elements, and ...
