The cast of characters, GUTS, is entertaining and interesting. Tiga himself is a decent design with decent fight choreography. And some of the kaiju designs are excellent. But there is little to no overall plot. Maybe about 5 episodes total up through 41 have involved Tiga's origin and the legacy that links him to Daigo. There are so many, and I hate to use this term, filler episodes that it isn't even funny.

Everything is so bland. Every alien invader episode is exactly the same as the one form 3 episodes further back except it's a new random breed of alien trying to do the same thing the last one was. There's no originality. Every couple of episodes is the same over and over.
