The Sirens of Time is a bit of an odd duck. At the time of publication, it is pretty understandible that Big Finish would still be working some of their kinks out. It is impressive having three doctors back in action right out of the gate, but there are issues with this audio drama that I feel would be later addressed. It's an unfortunate trend among fans to want to go in order of the monthly range, but it really isn't the best foot forward for Big Finish audio and I wish people didn't view this as a good jumping on point. The story is quite unevenly paced and I definitely tune parts of it out after a while, but it certainly has its moments and hints of the potential for these types of audio drama, and the outstanding quality that would eventually come out of Big Finish.
