The UI is practical, which a skill based game like MonHun needs, with the emphasis on giving you the important information all the time (as opposed to just flashing when you get hit because when you're not it doesn't matter due to auto health regen like in other games or whatever the hell you play) and keeping it fully visible (hence the primary colors). Even so, it can all be moved to the bottom screen as has been said multiple times already. And what could have been more compelling about a screenshot of someone mining ore (no, he's not attacking an enemy, lol) from a random rock in a non descript tiny underwater part (and hence with lowered visibility/blurryness added) visible on the screen? It's not like every walking moment in Monster Hunter (or any game) has a badass monster, an epic attack pose, and a wondrous background to drool over. Especially when the dude isn't even going for a hunt in this case. How about at least watching a trailer before you spew ignorant trolling bullshit?
As for the graphics, it's Tri G. That is, an expandalone to Tri. It looks like Tri, one of the prettiest games on Wii. Some toned down (mainly the textures, weirdly, considering 3DS has more ram than Wii) some improved (proper shadows) and in 3D. That you handpick some not so great screens to whine over doesn't make the game, or even the series, which has always had great artistic qualities, fantastic animation, and incredibly satisfying, simple yet deep and challenging gameplay that isn't for ignorant fools, ugly or bad. And lol @ the Japanese developer hate on the visuals, especially Capcom which has made some of the most beautiful games of the generation, with titles like RE5 easily outclassing PC titles that require much beefier PCs, especially in terms of polish and making sure almost every element is on par, more or less the opposite of Western developers' diamonds in the very, very, very rough, as the most renowned examples, Crytek's games, so gloriously demonstrate to all.
