I have to say I was very impressed with the premiere.
So far, I think Danson is doing a great job in the supervisor role, he asserts both an authority and a sense of humour which is something the show was desperately needing at the end of last season. I won't say whether I feel he's saved the show until I've seen a few more episodes but so far so good.
The writing was a significant improvement over last year as well. Greg particularly has livened up and I was strongly reminded of Greg from before Season 7, where they began to tone his character down. There is also a much larger sense of light-heartedness which nicely takes us back to the show in its earlier days. There are faults with the episode, but I blame that primarily on the fact thatIn a Dark, Dark Housewas ended so sloppily so there are still a few loose ends, but I hope the tension eases over between the team and we get to see some great teamwork in upcoming episodes.
The tram case was pretty decent, although I realise that the crimes needed to take a slight backseat in this episode to introduce two major characters, however I do feel the conclusion was rushed slightly. The B-case appeared very rushed, daft and kind of pointless, however, I can see it as a way to give Sara and Greg some screentime, so kudos to the writers for giving everyone an equal showing. (Something which was seriously lacking in the past three seasons.)
Overall, I feel Season 12 has gotten off to a pretty decent start. Whether I feel Ted Danson has managed to fill in the hole that CSI was digging itself into at the end of Season 11, I'll decide in a few more episodes, but nevertheless, if you were disappointed by some of the more recent seasons, you'll be relieved to know that73 Secondsbreathes a bit more life into the show.
