A quick review

Reasons to see Transformers 3 (in no particular order):
1. Giant Robots
2. Leonard Nimoy
3. Alan Tudyk
4. Sam was dumped by Mikaela (off-camera)
5. All of the technical achievements of TF2 without the raunchiness

Reasons not to see Transformers 3 (in no particular order):
1. Very long (2:37)
2. Fairly linear plot
3. Racefail (old stereotypes out, new stereotypes in)
4. Poor continuity
5. Terrible, Terrible Physics (worse than the '85 cartoon)

And if you do see it, don't bother with the 3D. That was a total waste of money.
