Steven Moffat, Doctor Who’s new showrunner, seems to be working overtime. Having written 75% of the season thusfar, each of his entries are solid, if not superlative. Two weeks from last Saturday, the Doctor’s past will meet with his future, thoroughly confusing his present companion. Confused? So was I, but in a good way.

“The Time of Angels” heralds the return of River Song (as opposed to Riverdance; no step dancers here), the mysterious professor from last season’s “Silence in the Library” by Mr. Moffat. River is interesting to the Doctor, and a bit scary, because he keeps meeting her in the “wrong order” in time. The last time they met, Mr. Moffat’s “Silence,” River died. This is further back in River’s timeline (obviously) but further forward in the Doctor’s. They each know each other’s future, and neither are talking. Still confused? Good.

The story also heralds the return of the Weeping Angels, statues that move when you’re not looking. Ooh, shiver. Two seasons ago, Doctor Who introduced us to the Angels (and to Academy Award nominee Carey Mulligan) in the exquisitely creepy “Blink.” I won’t say how, but “Time of the Angels” ups the ante considerably in making the Angels more deadly than ever.

The story’s well-paced and full of the creepy-factor we’ve come to expect from a Steven Moffat story, though the story suffers somewhat from a rather boring cadre of special forces operatives from the “Church” of the 51st century, a “Bishop” and his “clerics.” They seem somewhat ancillary to the story and succeed only as bodycount, as a couple of the cannonfodder clerics fall to the eponymous Angels.

Matt Smith continues his fine performance, somewhat more petulant than the last Doctor, and in some cases downright flirtatious. Alex Kingston is in fine form as the puckish River Song. And Karen Gillan continues to delight, particularly with her room-lighting grins.

And it still delights the family. My son, four years old, was giddily cowering behind the couch, just scared enough to run behind the furniture, but not scared enough to cry or beg me to turn the TV off. The pitch is just right.

Unfortunately for my son (and for me) the episode ends on a cliffhanger, and I’ll have to wait a week to see what happens. You’ll have to wait a few more. Wait with giddy anticipation – the episode’s a good one.
