Just finished watching it.
Spoiler!
I agree with the comments about the typical TVB ending. Everyones happy and all that bullshit. However I am surprised at how no one died, seeing as thats pretty much what happened in the last few TVB dramas I watched. And those passengers..I lol'd/cringed so hard at their "OMG WAAAAH HALP
"
Overall the entire series was just meh. I was looking forward to On Call 36 2, but seeing as how TITS2 was way overhyped, I have a feeling On Call will probably end up like this one.
