I’m unsure exactly why anyone would want to buy Anaconda on Blu-ray, especially this being a double dip for Mill Creek, unless you fall into the category of finding this to be some sort of classic so bad its good kind of flick.
Sharknado 2: The Second One is a great entry into the series and is a whole lot of fun through and through with great in-jokes and some wonderful cameos that were great to see (particularly Robert Hays in a fun callback to Airplane). This obviously is not something to take seriously and is especially fun to watch with friends making for a better experience.
