So I noticed how I only comment on the titles that I dislike and thought that I should try being positive for a change xD
Fake must be one of the first manga titles I've ever read because I remember reading the translation to my language along with the scans. I also remember that it fascinated me, thrilled me and took me along for an emotional ride along with the characters.
Now, that is quite common thing when one is young (and believe me, I become embarrassed when I remember some of the titles I used to like), but Fake stayed with me for years and the books belong to my prized collection that I'm never going to give up.
Some people say that the art takes some getting used to, but I actually love it (Matoh-sensei's new art style on the other hand...). It is sharp and masculine without being straight up bara and you can forgive the occasional flowery background. Now I like my cutesy, flowery, long-haired beauties, but tiny cute cops with huge eyes make me laugh (I'm looking at you, Tokyo Yabanjin).
Which brings me to the setting. Cops are usual... non-fictional foreign countries less so and the combination of the two is not something seen daily. And when it is done (mostly) right and you actually believe that Dee and Ryo are chasing the bad guys (or running from the bad guys, more likely) through the streets of NYC not Tokyo in disguise, it is very refreshing. But hey, I'm not from around there so who knows.
The story is well paced with an interesting plot and there is plenty of comedy and action all along. The characters are all likeable (yes, even Berkerley Rose) and pretty soon you find yourself rooting for them... or wanting to beat them up when they do something stupid xD The slowly developing relationship between Dee and Ryo is wonderful, sweet and realistic. Actually the dynamics between all the characters are well done and it's nice that 99 percent of the characters aren't gay.
Tl;dr: If you haven't read Fake yet, do it. You might even like it, I know I do xD (and pls forgive me the lame pun in the subject lol)
