I was pretty dissapointed by this season. I REALLY wanted to like it. From the first promos to watching Magiranger, I was really hyped up for it (especially after SPD). At first it was okay, not particularly good or bad either way. Then it started to get a bit better around "Petrified Xander," only to have one of the worst extra ranger debuts in "Long Ago." After that, it was kinda meh up until "Dark Wish" to "Heir Apparent" (which I guess I would consider to be the peak of the season), but then it became mediocre to downright awful for the rest of the season.
It could have been great, I liked the idea (although, I said the same about SPD), but in the end, it was just... blah. So I guess I'd give it somewhere around a 4 and a 6, so... 5/10. Come on, Bruce and Co., PLEASE don't screw up Overdrive like Mystic Force.
