Bad. Here's a character run down for ya.

Rating: 3/10 (22 June 2009)

First of all I would like to state that I am not a hardcore fan of Transformers. I watched the show when I was very young but I grasped the main concept and knew most of the characters. I also loved the first transformers movie, that much that I saw it well over 5 times at the cinema (discount). Seeing my fave characters on the big screen was fantastic, even if they weren't completely accurate to their g1 counterparts it was great to see them live action.
So here comes the sequel boasting more robots, more action and a more faithful movie. Well they got the first part dead on. There's so many damn robots in this movie that they forgot to properly introduce them, or even bother with character development. The action is packed but it lacks heart. It's just a slugfest of CGI models dancing around with explosions all over, at least in the first one you could tell what was going on. Anyway enough of this, here's the run down for those people who want to know how the robots turned out.
Jetfire: An old robot that acts like an old war veteran. Insert old man gags here. Whines and moans for a good length of the movie constantly while hobbling around on his "walking stick". Teleports Sam and friends to Egypt somehow which is never explained.
Arcee: Seen on the introduction for a minute or two, appears at the end for literally two seconds before getting shot and never seen again. There's actually 3 of "her", again never explained. Her alt form(s) are motorbikes.
Mudflap and Skids: Meet the god damn stars of the show! These two wise cracking idiot robots get more screen time than anyone and are constantly making "pussy" jokes. Childish as hell. If you though Jar Jar was bad Ooooh boy you're in for a surprise! Makes you wonder what they were smoking when they decided to RUIN the movie with this duo.
Sideswipe: The new coolest looking autobot who gets seen here and there but again is never formally introduced. Shame because his design looks pretty cool. But no screw that, make way for the MUDFLAP AND SKIDS SHOW! What a waste...
Jolt: I didn't even see him once. I'm not even kidding, the wiki has details on him but I can't remember him at all.
Wheelie: Another comedy character who fills the role of the "gremlin" in this movie. Annoying as hell but at least he's involved in the story, unlike the twins.
The Fallen: The biggest cliché of the movie sits on a thrown practically throwing out orders to Megatron as if he was Emperor Palpatine's apprentice (he actually says "my apprentice" too... UGH). Apparently one of the "Primes" who can only be defeated by the "Primes", aka Optimus. As soon as Optimus is out of the way he flies to Earth only to get obliterated in minutes in the last fight.
Soundwave: HUGE let down for the many many many Soundwave fans. He sits in space as a big satellite and talks to the Decepticons. That's all he does. He sends Ravage down, who is kinda cool.
Constructicons: They form devastator, which can be seen in the trailer. The Constructicons themselves don't talk or do anything, and are there simply for the "omg they combine into 1!!" factor. He dies in seconds and has dangling metal balls. I wish I was making this up.
Others: Not even worth thinking about. Any other robots are there for only a brief moment, aren't introduced or anything. Instead the time that could have been used to introduce them are filled with more jokes and "dawson's creek" moments. I will say that Starscream is A LOT better in this, but seeing Megatron bow before another villain and call him master makes me cringe.
Don't get your hopes up folks.
