I like this episode as one that tries to break new grounds in the established Doctor Who series, getting out of the comfort zone. Here we see the Doctor in another episode flying solo and how this affects his judgment without an opposite like Donna. The companion always challenges some critical decisions of the Doctor. The episode ending shows that and how this might affect his future. It is clear special effects and sets have improved a lot through seasons and this episode has a cinema film feeling in its execution. The enemy here is really scary and not always when visible. Acting is excellent and Mr Tennant shows very well Doctor's conflict at the end. Can't wait to watch next episode.
