I've only seen the episodes subbed by TV-N, but so far I'd have to say it's my favorite Sentai. It might not have the drama of Jetman or the fight scenes of a Dairanger, but there's something about the simplicity and whimsical nature of it all that really does it for me.
MegaRed might be one of my favorite Red Rangers. Instead of the "Captain Cardboard" type or the Red Rookie we've seen a lot of lately, we have someone with the unwavering character traits of a leader, but also all the traits of a goofball slacker. He's the first one to jump in whenever his friends are in trouble... it's just sometimes that "jump" could have been better planned.
So many great moments in the first few episodes: Kenta making Dr. K buy him barbecue in payment for being a ranger, Dr. K ignoring Miku's request for cake, Kenta's fight with the Kendo team... the list goes on. Really hoping to see more.
