This movie is just better because the previous entry is more campy than horrifying, while this one, It's still campy but you can still be terrified at the same time.
The first segment, Ahas is a great entry, it rips off a myth that is surfacing in the Philippines where a Mall was a home of a Snake Man while in this one, It's a Snake Lady that was born from a side effect of a lucky charm. The segment is not that very frightening but maybe the theme of a monster lurking from the sides of a mall can be scary to think about.
The Second Segment, Ulam is probably the more scarier in this anthology of stories, It follows a family staying in a new house where the cook poisons the family in their dish that slowly turns them into monsters and the husband and wife almost kills other, It's very twisted, disgusting and bloody.
The Third Segment is probably the most campy of them all than scary, It's still a nice concept but it's not done properly, they did a good job on this one but It can maybe better. It's about a baby monster that was given birth on an airplane then slowly kills most of the passengers. It's very campy because of the bad CGI action of the baby monster but other than that, It's still a good watchable segment.
Overall, all of the entries are watchable, you can watch all 3 in one sitting just because all of them are good.
Ahas - 6/10
Ulam - 7/10
Flight 666 - 7/10.
