I had read that this sequel was just a cut and paste of the original script, only that it takes place in Thailand this time, and now that I have seen it, that is pretty accurate. And the sequel lacks a lot of the charm, humour, and smart comedy that the original has.
While it's not Justin Bartha who is missing this time around, he is missing from all the craziness, and you can see why - his character is so flat and boring, it makes sense that he is barely seen or heard from in this. Any time he is seen on screen, it's kind of painful to have to listen to him, he's so dull.
The situations are ridiculous once again, but it's just not on the same level as the first movie, which I can watch again and again...and again, and laugh myself silly each time. This new movie, we had to keep pausing just to get through it in one night. It was tough to sit through, ridiculous in a not so good way, and really, not worth watching once...and definitely not a second time.
