Tell me if you've heard this story before: dorky guy can't confess to the girl he loves, mostly because he lacks experience with women. One evening, while bathing and worrying about his lack of experience, a nude alien babe pops up out of his bathwater. Problem solved!
This harem-ish ecchi comedy is the type of anime that jaded anime fans like to turn their noses up away from. You should know that these First Impressions are coming from a fan that, while being one for decades now, is not at all jaded, and likes to watch something simple and fun sometimes. If you couldn't already tell, I really like To Love-Ru so far.
To Love-Ru likes to pull fast ones on viewers, never taking itself too seriously. Even the name (said as "Trouble") is tricky! The first episode opens with some very 1980's styled animation of a space chase as some girl in a spaceship is being perused. They're channeling Star Wars here. If you're not prepared for it, you'll think "what is up with this crap animation?" But, if you're that "serious" of an anime fan, then you probably didn't even bother to watch To Love-Ru in the first place. Those that stick around would soon see that they drew upon this old style for fun.

Worries of animation quality are (mostly) thrown out the window in one of the most fanservice-packed openings I've ever seen in my long history of anime fandom. It looks great, and is funny to boot! The credits are placed on the tags of swimsuits and panties and socks, or right next to (or on) breasts or panty shot areas on other surfaces. I laughed out loud at a couple of the placements, and I continued to giggle as I mentally pictured countless anime snobs stopping playback before the episode fully started.
The story is, naturally, cliché packed. The girl in the spaceship, Lala, managed to get away via some kind of warp. This warp puts her right between the legs of the earthling bathing male lead, Yuki Rito. Of course, when she materializes, Rito just happens to be holding Lala's breasts. You just can't make this stuff up... because it's all been made up before.

It turns out that Lala ran away from home, planet Deviluke. She is heir to the throne, but she can't be bothered with arranged marriages. So, to Earth she goes. The people perusing her are actually trying to bring her back home. Poor Rito gets roped into this: just as he's confessing to the girl he's loved for so long, Lala appears in front of him, accepts his confession for this girl, and promises to marry Rito.
In between the plot-driven scenes are a ton of head-scratching moments that help differentiate To Love-Ru from the old "alien girl" anime. This show does have the obligatory magical girl-ish transformation, but this time around a "costume robot" of Lala's invention named Peke transforms to cover her naked body. And it talks! Even more bewildering is Lala's other invention, a giant robotic octopus vacuum, which she uses to suck away her perusers. WTF?
Plain and simple, this is comedy ecchi. Boring boy meets lively alien girl. It's an old story, but it's supposed to be. What's great is that To Love-Ru has fun with it. And yes, there is a ton of fanservice for one episode. The opening and ending sequences (the end is all swimsuit shots) are nothing but fan service. But that's the point, right? There's boobs, pink hair, cute characters, fun music, and nice animation. Oh, and it's funny! If you're fond of the phrases "repetitive" or "too predictable" or "too much fanservice," then don't bother with this. Otherwise, watching To Love-Ru will be no trouble at all for you.
Hence, I chose Kanokon over To Love-Ru.
