I didn't go to the cinema so I've seen it for the first time today. Here's my short review. I can't say i hated T4 but it was bad for Terminator series standards. First of all, why do all the Terminators in this movie make strange sounds (humming, buzzing, squeaking etc.)? Is this supposed to be cool or remind the audience about Transformers or what? That's not the biggest problem, because they don't look and "feel" scary. You don't get goosebumps whenever you see a Terminator. Instead you're laughing quietly at smart robots running around the screen. The cast of the movie was not great (especially Connor's girlfriend was bland) and the scene with Arnie was AWFUL (way too short and way too cheap). Other things I didn't like about the movie:
- soundtrack - sometimes they were fighting for their lives and a random action tune was playing in the background
- the silent kid - guess I'm not the only one here
- Terminator motorcycles? WTF? I can understand the large robot and the leeches but what's up with bikes?
- the whole plot with Blair wanting to help Marcus needed more development so that the viewer would understand why she risked her life for a machine
- trying too hard to put as many famous quotes from the previous films as possible
What i DID like:
- Kyle Reese & Marcus (I loved the fact that his character got more screen time than John Connor)
- beautiful apocalyptic sceneries
- Moon Bloodgood

(I also thought that I will add Michael "Sam Fisher" Ironside to this list but his acting was almost as bad as Dennis Quaid's in GI Joe

)
- nukes
Overall I'd give it 5-6/10 only because I'm sentimental.
