Genseishin Justirisers Souchaku Chikyuu no Senshitachi (GBA)

Gen Sei Shin Justirisers is a TV show. I even saw a few episodes of it, years ago, when I first started watching fansubbed tokusatsu shows, and would download every show I could find. I can't really remember many specific details about the show though, other than being like a slightly more seriously-toned version of Super Sentai, with slightly lower budgets.
THis is a game of it. It's a simple beat em up, you can pick any of the three Justirisers: Riser Glen (red, has a sword), Riser Kageri (blue, has a katar-like weapon and is the token girl) and Riser Gant (black, has a gun), you get to choose your character at the start of each stage. While you're playing, you can choose between fighting with your fists or with your character's weapon. There's no reaason not to use the weapon at all times, though. Especially if you're playing as Gant, obviously.
You can also jump, do a sliding attack across the ground, and use a special attack. The special attack is powered by an "energy" bar underneath your health bar, but there's plenty of items to top that bar up, and the game's so easy, the only use you're likely get out of you special attacks will be as a way to kill the bosses more easily.
The game shares some similarities with the Playstation Super Sentai games (which I should really get around to, some day), in that it splits the action between fighting as the heroes themselves against human-scale jobber enemies, and piloting a giant robot against giant enemies. The giant robot fights aren't very interesting, though: you tap the B button to build up a power bar until it's full a few times, then press A to unleash an attack (there are four attacks, you get the more powerful attacks by filling the power bar more times). In theory, there is an elemen of risk involved in these fights, as the more time you spend building up power, the more likely the enemy monster will attack. Unfortunately, they rarely do, and you can just keep charging up and firing your most powerful attack until the enemy dies.
The game is okay to play, it's not horribly broken and it doesn't have any awful chore-like grinding or anything like that, either. It's just absurdly easy. It was probably made for 10 year old boys, but that's hardly an excuse for this level of feebleness. It's a little more than an hour long from start to finish, and I'm fairly sure I didn't lose a single life along the way, and as I've mentioned before, I'm not really very good at games.
