Return of the Teenage Werewolves

What would the summer be without the werewolves to brighten it up?  And with the return of MTV's Teen Wolf tomorrow night for its fifth season, you get two hours of action with Scott and his friends, or at least those that have survived the show to this point.  The days of Buffy the Vampire Slayer are long gone when the regular crew stuck together until the bitter end, though I expect the bromance with Scott and Stiles will remain throughout the series.

So what does MTV have in store?  Here is the quick summary (which could have been written for just about every season):

On the eve of Senior Year, Scott and his friends find themselves facing the possibility of a future without each other, a next phase of their lives that might take them in different directions despite their best intentions. Little do they know that outside forces are already plotting to break the pack apart long before they ever see graduation. New villains that use a combination of science and the supernatural for a malevolent and mysterious purpose that will eventually pit Scott and his friends against their greatest enemy yet. 

This trailer for the new season provides a little more.  As usual, we have a completely different monster taking on the Scooby Doo crew.  Sometimes they show gets a little too creative with its foes, be it Japanese swordsmen or Mexican mystery curses.  This season it appears to be someone in a gas mask/scuba diving outfit. 

And just as characters die or go away on this show, new characters tend to pop up.  Last season we had the werewolf pup Liam, who will have a bigger role this season as Derek recedes into the background. 

Teen Wolf will have 20 episodes this season, with a mid-season finale as before.  So get ready for another dark romp with the gang.

Update:  The first episode introduced the insect-like enemy and flashed forward via Lydia to the dark events to come.  And we also caught a glimpse of departed Aidan, while meeting a new werewolf Theo who wants to join Scott's pack. So the senior year just got a little more interesting. You just wonder if Theo will make it through the season given the show's high body count.

Second Update:  Teen Wolf has been picked up for a sixth season.  Buffy the  Vampire Slayer, another great high school ensemble battling monsters, lasted seven seasons. Can Teen Wolf surpass this record?
