This is only the second C-drama I've watched, and of course, before my C-experience becomes somehow statistically relevant, a lot more time will have to pass, LOL...but I still think I'm seeing some trends, as compared to J-dramas (correct me if I'm wrong!): first of all, cinematography and photography/colors are much more relevant (and *ages* better!) in China; secondly, the music as well (intended both as OP/ED credits songs and, even more importantly, as the musical score accompanying the various scenes) is also, at least for me, tremendously better; thirdly, even with much longer dramas (this one, for example, with its 24 episodes - which make it a "short" one in China, BTW! - could very well be the equivalent of 3 to 6 modern J-dramas! - what with the new Japanese "standard" being shorter dramas made of half-length episodes), well, even with all that, Chinese writers manage to keep things lively and not boring; last but not least, traditional Asian values seem to still be at home in China, while in Japan they keep getting replaced by Western stuff at a dramatically fast pace.
All this said (and consider it a public explanation of why you're most probably bound to see many more C-reviews from poor old me in the future ^__-), this "My Assassin Girlfriend" also showed a coupla drawbacks (hence my vote - good but not perfect).
But let's start with its (many) good points: I chose to watch it 'cause I had really loved Xu Jie aka Jelly in "Waiting for You in the Future", and indeed she was good and funny in this one as well (so much so that I wonder why she hasn't done anything else! >__<). The rest of the cast was also brilliant! I've developed a huge crush for Chen Hao Lan aka Anna Hollen, who's gorgeous to look at *and* a pretty good actress! Ryota (weird name for a Chinese actor, LOL) was also extremely good, I'm gonna keep an eye on him too. But seriously, they all did great, even the minor roles were played well.
The music (see my considerations above) was also nice and catchy, particularly the opening credits song!
The cinematography was beautiful, both in the modern and in the ancient settings (my personal preference going to the latter...ah, those colorful silky costumes! Made my crush on the FL even bigger, LOL).
The script was mostly well done, though (here come the afore-mentioned drawbacks) I have to confess it gave me the impression that some parts were missing, as if they had planned it to be made of more episodes and had to cut some parts off eventually. This (which is totally a personal idea, so pardon me if I'm wrong!) might explain a coupla plot holes (which I might address in a comment later on so as to avoid spoilering anything in this review). Another (minor) problem I had was that I would've changed some small things at the end (just a matter of personal preferences, though).
All in all, a solid, funny time-travel rom-com graced with endearing main characters and some nice humor here and there. Not a masterpiece, but a pleasant watch nonetheless!
