Alvin & The Chipmunks 3: Chipwreaked - Boring, Forgettable & ZZZ Sequel

Alvin & The Chipmunks 3: Chipwrecked
Synopsis:
The movie started with the Chipmunks and Chipettes going on a holiday cruise with Dave (a slimmer Jason Lee). In the cruise ship, Dave bump into Ian (David Cross) who now works as the ship mascot - a bird and also to report to the captain of any misbehaving patrons. As usual, the Chipmunks and Chipettes started to create havoc and accidentally fly-off in a kite to a deserted island. Dave upon seeing the Chipmunks and Chipettes flying away, decided to rescue them but was also blown away together with Ian to the different section of the island. The chipmunks and the Chipettes decided the only way to survive in that island while awaiting help is for them to turn into their basic surviving skill. Along the way, the also found that they are not the only ones in the island. They also found a woman named Zoe (Jenny Slate) living in the island for about 8 years and in the beginning Zoe was found to be friendly and fun but she has a hidden agenda whereby she is searching for a lost gold treasures supposedly buried in the island.
Review:
I was anticipating this movie as i found that the 1st movie: Alvin & the Chipmunks is a nice, good and cute family movie especially Theodore. Then, 2nd movie is a bit bland, usage of same formula and plus the introduction of Chipettes, it somehow took away the cuteness and fuzziness of original Chipmunks. So, in the 3rd movie, i expect the director to throw the Chipettes away and stay to the original Chipmunks but somehow it became Alvin & the Chipmunks & Chipettes again. Worse, the direction of the movie is simple, so the director has to put in a lot of silly things like Alvin creating havoc scene on the ship (non of the movie goers are laughing at all, heck the kids aren't even laughing), a lot of singing here and there but not so memorable- all these just to prolong the movie hours. In the end, it was a disappointing movie and it makes me wonder if this Alvin & the Chipmunks franchise has exhausted all ideas even after just 3 sequels. 
Verdict:
I give this a 1.5 star out of 5. Yawn! Forgettable movie.
