Haven't watched an actual anime series in a while. Just haven't been in the mood. However, one of my favorite anime series of all time, Full Metal Panic, got its LOOOOOOOOONG-awaited 4th season, Invisible Victory (Get it?), last year. I never got around to seeing it since I was waiting for the home video release with the English dub. Well, that BluRay release finally came out this week, so I finally checked it out.
Yeah, it's pretty damn good, and it's good to see a semi-gritty anime mecha show again after 13-14 years since the last season, The Second Raid. In a curious move, this season is a DIRECT sequel to the 2005 previous season, with absolutely no time spent catching newcomers up on the premise of the series, Sosuke & Kaname's relationship, Mithril, Amalgam, Arm Slaves, Lambda Drivers, Whispereds, the events of The Second Raid, etc. If you didn't see the previous seasons, you'd better get on that. Hell, it's been so long since Second Raid, I didn't remember some of the newer characters from that season.
The 12 episode season is broken up into roughly 3 arcs: Amalgam's assault on Mithril; Sosuke's globe-trotting in the aftermath; and the resulting raid on an Amalgam base. The 1st & 3rd arcs are generally well-paced and move the story forward considerably from The Second Raid, but the middle arc feels really out of left field and doesn't feel like it approaches having a point till near the end.
Quite possibly the most frustrating thing about this series is that the fans waited 13-14 years for this thing (depending on the region), and this still isn't the conclusion to the story. There are still 3 or so of the original light novels to adapt, and there isn't any indication that's going to happen just yet. This show's changed studios twice already, and it looks like it probably will again now that Xebec's been sold to Sunrise.
That said, there's certainly a big "well, it's about time" element to the finale long-time fans will appreciate. Tessa, the submarine captain, also gets plenty of screentime to show what a complete and utter badass she is despite being this small, frail teenage girl. Chris Paton & Luci Christian are still absolutely pitch-perfect as Sosuke and Kaname, but unfortunately this season doesn't give them much to do together and Kaname spends a huge portion of the season mired in depression and self-pity. It gets a bit tiresome.
I realize it's probably not the most interesting write-up on the show, but I'm trying to avoid spoilers since this is a series I highly recommend if you've never seen it and has shifted tone a LOT over the course of the existing 4 seasons. What started as this fish-out-of-water comedy with occasional gritty mecha fights shifted to screwball comedy in Season 2, then deathly serious drama in Seasons 3 & 4. Hopefully, we get Season 5.
