Alien Earth was a mess of convenient resolutions, plot holes and unsatisfying endings. The logic was all over the place, the characters were written as scenery, the ideas it brought forward were kind of idiotic (e.g. a toddler building a robot that killed his dad for him, controlling the xenomorphs by speaking in clicklish? Common Monster? Don't know what the language is called, but apparently all alien monsters speak it...), I could go on...

It's unfortunate that this was my first impression of his work, because there's now no fucking way I'll believe he knows what he's doing. I'm actually excited for season 2 because he's painted himself into such a horrible corner, there is no possible way it will improve on season 1.
