Did You Know?


It was widely rumored in the spring of 2004 that alternate endings for the third season finale were filmed. Scott Bakula went so far as to suggest on a major talk show that in one of the endings filmed - to be broadcast if the series was cancelled - Archer died. Later, Bakula denied that any alternate endings were filmed, despite the fact that, had the series been cancelled at the end of season 3, it would have ended with a cliffhanger. See more »


Travis, flying down to San Francisco in 1944, says everything "looks normal." But the inhabited regions of the Bay Area would be dramatically smaller, the Richmond-San Raphael Beidge (built 1957) and San Mateo Bridge (built 1967) would be missing. See more »

The entire human race depends on Hoshi?! CRAP!!!
10 April 2015 | by (Bradenton, Florida) – See all my reviews

The important thing to know about this episode that it pulls out all the stops and EVERYONE and EVERYTHING comes together at once to win the day for the human race and the nascent Federation...and in the end, it all boils down to Hoshi!!! NO!!!! Considering what a whiny thing she's been, then it looks like we are all screwed, right?! Well, maybe not.

The episode begins with the super-weapon coming towards Earth--with Archer in Degra's lightly armed ship in pursuit. At the same time, Enterprise is on a mission to destroy a sphere--and hopefully destroy the network of spheres.

In this show, there are lots of surprises--including a visit from my favorite character from the series. This one will keep your pulse pounding and is THE show to see from the series. A definite must- see and a thrilling finale to the Xindi war.
