I found T4 Salvation to be OK. It takes all the bits and pieces that have been told about John Connor's future and ties them together, picking the story right up with the battle between humans and cyborgs. Fast moving and not all that bad. The usual complimentary love interests are there to attempt to move the movie forward when they can't think of anything else to do, but then that has been the case with all the Terminator movies. Even the complimentary "Arnold" showing up as a computer generated animation was both amusing and interesting. Not really that bad a movie, especially for the matinee price.
"The Informers" is a bizarre movie in the "Crash" genre although it leaves you with the emptiness of the early 1980's drug/sex scene. A very graphic and intense look at the lives of those who have nothing else in life but sex and drugs, with the shallow emptiness of the Hollywood crowd and the RocknRoll crowd mixed together to reinforce it all. If you liked Crash you will find The Informers interesting. There are no characters to like in this movie but then sometimes it is best to tell a story exactly that way.
