With Steven Moffat taking the helm over from Russell T. Davies I was hoping for something good and thankfully he didn't disappoint with the fifth series.
Matt Smith is a great choice of casting for the Eleventh Doctor, he plays him with a weird quirky energy, and at times funny, and a little arrogant but other times very compassionate. One of the best things he brings to the Doctor is he has a nice understated way of delivering his performance, from that point of view took to him quicker than I took to David Tennant whom I grew to like as he progressed. Karen Gillan was also a great addition to the cast, some people thought she outshined Matt Smith, but I think they are both equally good.
Overall there are some really good stories and one or two not so good. The opener "Eleventh Hour" is a really good start to the series and introduces Matt really well, as well as the lovely Karen Gillan as Amy Pond, and yes all of sudden bow ties do seem cool (although he does use the phrase a bit too much!). "Victory of the Daleks" is also very enjoyable despite the outrageously garish coloured daleks, I'm surprised Russell T. Davies didn't think of that, and Bill Paterson is really good in it, but the actor playing Winston Churchill while I liked what he did, he seemed to play Churchill a bit too cheerily, the man was after all a depressive type of guy. The "Time of Angels and Flesh and Stone" was a good two parter that re-introduce River Song (Alex Kingston looking good!) to the show. And one of my favs of the series was "Amy's Choice" where we see Amy's alternate future with Rory. The Silurian two parter was probably the weakest of the episodes though. "Vincent and the Doctor" also received alot of praise but I think it was not bad, but overall just not bad, but I did like Tony Curran's potrayal of the Van Gogh as he did play him as a tormented genius, and the story has a nice poignant ending between The Doctor and Amy. "The Lodger" is another of my favourites where the Doctor becomes a new lodger in a house which has some evil force living in it, I also liked James Corden and Daisy Haggard's nice chemistry and their romantic storyline. But the final two parter is a real cracker "Pandorica Opens" and "The Big Bang" provide alot of surprises and twists, and it ends on a good note which promises more great stuff to follow.
So overall series 5 sees Doctor Who carrying on strong, and Matt Smith despite being the youngest actor to play the Doctor, really makes the part work, and still manages to capture the Doctor's seniority and maturity, which is at odds with his appearance. Also the new TARDIS set is cool (with a typewriter and a tea kettle no less!) and Murray Gold's new incidental music is great, the eleventh doctor's new theme is great, although the new version of the actual theme music isn't that great.
But this is a really good series, if you have seen the others and not this one yet, buy it!
