Episode four of Ultraman Tiga features one of my personal favorite monsters throughout the series in Ligatron. The suit for this monster is incredibly detailed for a creature for a tv show. You can distinctly tell the design came from the idea of a converted spaceship, which it was. There's so much attention to detail to the skin of the creature that it has the metallic look but not being overly so like say the MechaGodzilla. Great villian.
Most important to this episode is the plot and while it is a little far fetched that we're sending ships to Jupiter, the central idea that the monster still contains the spirits of the three dead astronauts is awesome. Ligatron proves to be more than a match for Ultraman and it is not until the souls reconnect with humanity that he can defeat the monster and that is great. Some key sequences with the spirits interacting with their families really shows the importance it is placed in Japanese culture. We also get some minor character development for Shinjoh in this episode as he is opposed to attacking the monster because of this. Great stuff!
Overall decent effects, an interesting monster (anybody notice that Ligatron's hands bear a striking resembalance to Gigan's from the Godzilla series), and a solid story make this episode a winner. 9/10moreless
