The blu-ray set is a three-disc set and reproduces the content of the original DVD releases. Again, the individual seasons are not available on blu-ray; you can (at least as of this writing) only get the blu-rays in a complete series set. The A/V quality of the blu-ray release is very good. The extras are all included on the final disc. Those include clips of Norm talking about his wife Vera (who never appear on screen), clips of Carla making fun of Cliff, clips of Fraiser's key moments in the season, a virtual tour of the bar, and a tribute to Nicholas Colasanto (which features interviews with Ted Danson, George Wendt, and Rhea Perlman talking about Colasanto and what he brought to the show and the character of Coach.
The series really found its footing by the third season. The show continued to be a mix of procedural weekly storylines and longer serial arcs. While the show's focus remained on Sam and Diane's relationship, the writers continued to expand the storylines for the supporting characters, particularly Cliff and Norm. Each of the supporting characters received at least one show devoted to him or her. As was the case in the first two seasons, there are definitely jokes that would probably not be used if the show were made today, and there are quite a few adult jokes, so while the series is mostly good-natured and wholesome, it is not entirely family-friendly. Ultimately, if you liked the first couple of seasons, this one is worth watching.
