Some other reviews I found while us Americans are still waiting for Dream Team:
Gamespot gave it an 8/10, saying it was a polished, if very familiar Mario and Luigi experience
Gamesradar had a similar grade, 4/5 stars, and similar impressions, praising the game's quality production values and refined mechanics, but found the experience very familiar, and surprisingly linear.
CVG handed out an 8/10 as well, singing the praises of the creativity on display in such a charming, witty fashion, and the active battle system that keeps the player invested in even the most minor of scuffles, and really liked what 3D added to the game, mentioning how red shells are easier to kick back when you can see the depth of the screen. They weren't so crazy about the Dream world puzzles, finding them very simplistic, and while there's lot of things to collect and gear up with, the stat changes aren't as robust as they'd liked.
Edge 7/10 review went up online, and I have no idea what review that other guy read; they don't even mention Bowser complaints until the end. They take issue with the 2+ hour onslaught of tutorials that treat you like you never played a video game before, the 3D overworld is a bit ugly(a little antialiasing would got a long way here), and noting the spritework doesn't look as good the DS games. They don't think it's as funny either, stating how boring the Pi'illos characters dialog is, and how the new badguy Antasma doesn't hold a candle to Fawful. Despite all that, they felt the game delivers what M&L always does: an irreverent take of the Mushroom Kingdom, and an absorbing, addictive, active battle system. They also praise how you can cancel out of 3D mode for special attacks with the R button, a nice thought by AlphaDream.
