Beverly Hills 90210 was not a show I had grown up watching as I was only around 9/10 when it first aired and never got into even during my teen years, however it has stood the test of time as a fun primetime soap opera.
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.
