The future of humanity is in peril, as they are confronted with the threat of an intergalactic clash with a warrior-like alien race, and the only one who can save them is... Captain Tylor?! Join a crew of misfits and rejects including an alcoholic doctor, a gorgeous nurse, an anal-retentive commander and a bunch of really stupid marines as they try to make it out in space and to discover whether their captain is a misunderstood genius or a total moron like he seems to be.
Very similar stories, the main character ends up joining the military and succeeds through dumb luck. There ends up being several women fighting for the captain's love and attention. Both space/spaceship themed.
Both shows are about rather idiotic guys who unexpectedly wind up as the captain of a spaceship, constantly get into trouble, then constantly save the day through sheer luck.
Follow the adventures of each main character as they are tossed into strange hilarious situation after another and somehow find a way out of it. The cast is fun and always willing to give the clueless captain a helping hand. Both of these titles are sure to match the viewer's tastes.
While Captain Tylor is miles better than Tenchi Muyo! GXP, the two series have a lot in common. Both male protagonists are bumbling buffoons (Tylor is lazy while Seina is impossibly unlucky), but because of their uncanny ability to wiggle out of trouble, that's how the "monster of the week" episodes come together. There's also a harem element to both, and both are primarily set in outer space.
Similar concepts, though I felt Seina Yamada in GXP was more of a clueless idiot. The strenght of Captain Tylor lies in the fact that Tylor isn't an idiot; He just holds a different than normal outlook on life and the series true strength is in keeping you guessing whether or not that is a good thing.
In a far and distant future, men and women have become mortal enemies. Each living on seperate planets, an interstellar war is being fought between the two very different peoples. Hibiki, a mere 3rd class worker, finds himself in the middle of a huge space battle, facing the nemesis of mankind: Womankind!
Both stories contain a male protagonist that goes from an unimportant nobody to playing a pivotal roll in a much larger conflict. (In one story the boy is a mechanic and in the other the boy is the unluckiest boy alive). Both stories involve side drama (and comedy) between the main character and several female character. The both also involve space/spaceships etc...
I'm not really sure what to write here. I mean both of the series felt somewhat similar, but I can't think of any good reasons why. Nonetheless, if you liked one of those two anime, you might want to give the other one a shot.
When Akito Tenkawa went looking for answers about his parents' deaths, he had no idea that he'd be indoctrinated into the spaceship Nadesico not only as a cook, but also as a mecha pilot – a job he wants nothing to do with! Alongside his childhood friend Yurika, stoic Ruri, otaku Gai and other misfit crewmates, Akito and the Nadesico crew find themselves in the middle of a brutal war against both the dreaded Jovian Lizards, and the military itself, who wants the civilian ship under their control...

In the future, a devastating event known as Second Impact has destroyed Tokyo as we know it, giving rise to Tokyo III - a city under siege by mysterious lifeforms known only as Angels. Mankind's only line of defense are the Evangelions, a set man-made machines piloted by a trio of fourteen year-old teenagers, Rei, Shinji, and Asuka. The fate of Japan and the entire world now lie with these three children, though they might not have the power to save the most important thing of all: each other.
Though the tone between these two are completely different (one being deep, dark and philosophical while the other is a comedy), both involve a main male protagonist that is insecure and unimportant, though the world finds a use for them and they end up being extremly important. In both there is a main female charicter that the main character confides in and sees as a source of comfort as well as several other female characters that act as potential love interests and/or sources of conflict with the main male character.
Chitose Hitotose was orphaned at a young age and is now in high school. He yearns for a family and a place to belong, but his long years of independence and isolation are setting his feet on a dangerous path. What is the solution that his teachers conceive? He needs a mother... but it's not just one, but five "Mamas!" Absolutely no one can discover that his teachers live under his roof, and he has to hide the fact from everyone, from the class president to the principal! With their maternal instincts in overdrive and mysterious pasts, can Chitose learn the lesson of happiness?
Both Happy Lesson and Tenchi Muyo! GXP feature a teenager who lives with a harem of female teachers. Neither of the series is good (though Tenchi Muyo! GXP might be slightly better), but if you liked one of them, then you might actually like the other one too.
