Your Gundam reviews have been entertaing Aion, if a little unfair IMO.
I would presume, having seen only the first ten episodes of the series (I'm waiting for some good fansubs or an offical release with Japanese language) that it's the case a lot was cut. I agree that Lalah & Amuro's relationship does seem very bizarre in the films, especially given that you get to see a relatively decent amount of her relationship with Char by comparison. Will you be moving on to Zeta, dare I ask?
Interesting to note I gave them 7,7,8 respectively at MAL... our rating systems must be a little different!
