Doctor Who superfan Lizo reviews the 10th episode of the fourth series - Midnight.
If you thought that Doctor Who couldn't get much darker of scarier this series, think again. Midnight is one of the most intense and disturbing stories we've seen so far.
It all starts off happily enough with the Doctor and Donna on the holiday planet of Midnight.
What's going on here?
Donna just wants to sunbathe, so the Doctor goes off by himself on a sight seeing trip with a group of strangers. And that's when the trouble really starts.
This is one of those stories where the less you know before watching it, the more you'll enjoy it.
Without giving too much away, writer Russell T Davies takes a beautifully simple concept and turns it into something filled with menace and terror.
It's a story that looks at different parts of the Doctor's personality, especially his never ending curiosity, while at the same time showing the risks and danger that that brings.
And it also highlights, with Donna not around for most of the story, how important his companion is to him. But the most terrifying part is how it explores how human beings respond when they're under intense pressure.
Midnight looks to be exciting!
It's great to see how Doctor Who doesn't always need lots of special effects and huge sets to succeed. This episode is mostly set in one room, which gives it a wonderfully claustrophobic feel.
And thanks to a brilliantly intense performance from David Tennant, this is an episode that's well up there with the programme's very best.
Five out of five

"It was OK but a bit disappointing since they made a whole 45 minute episode about copying each other. Other than that it was good."
Daniel, 11, Cambridgeshire, England
"I thought it was really good, but not the best there is."
James, 10, Middlesex, England
"This was an amazing episode and a brilliant effect because you didn't know what was after them!! Can't wait to see the return of Rose Tyler."
Kerry, 14, Southampton, England
"I enjoyed it but thought it wasn't really a Dr Who episode - more something from those freaky supernatural dramas. It was quite creepy how Sky and The Doctor repeated each other."
Megan, 11, Suffolk, England
"One of the best Doctor Who's I have ever seen. The repeating scared me so much I was hiding behind my mum! Did you see Rose trying to get The Doctor's attention?"
Rhiannan, 10, Lanarkshire, Scotland
"Loved it! Best episode so far, even though Donna wasn't really in it. It was so funny when they were talking at the same time. Can't wait for the next episode!"
Leigh, 11, Reading, England
"It was the most boring thing I have ever seen in my life. Bored from start to finish. Get your act together."
Ryan, 13, Oxford, England
"I say that was the scariest episode of Doctor Who this series yet."
Mark, 9, Rickmansworth, England
"I luvvvved it! I don't usually watch Doctor Who but I couldn't turn this one off! The woman on it was soo scary!"
Carla, 13, Cardiff, Wales
"I love the show, but in the library it was a bit complicated and I couldn't follow the story. In the crusader it was a little boring. But the show is fantastic!!!"
Shannon, 10, Sutton, England
"This was by far the scariest episode I have seen of Doctor Who. I think that it was even scarier than Blink in the 3rd series. I love the fact that Rose was in it and that she's coming back!!!"
Mackenzie, 14, Malibu, USA
"WOW! I loved it, one of my fave episodes so far. It was scary and I really felt sorry for the Doctor when he wasn't in control and everyone was shouting at him. It just shows how much he needs Donna, at the end of the episode he was really shaken!"
Georgina, 13, Kent, England
"I think this episode was a little misguided. I think it wasn't as gripping as other episodes have been. I think last week really seemed more like a season finale episode and so nothing could really beat that. The tension and brilliant comic timing between the Doctor and Donna was seriously missing!"
Manraj, 13, London, England
"I thought that this episode started off very mysteriously and exciting, but as the story progressed, I found myself a little bit bored. I mean, where were the monsters? Every good Dr Who episode has a beastie in it. The episode was good all the same, but no way near as brilliant as Silence in the Library, and the Forest of the Dead."
Emma, 12, Manchester, England
"I watched this episode with my friend and it had me shaking! The poor Doctor!"
Megan, 12, Llandudno, Wales
