Well, my 2 cents worth.
Have watched till epi 41 of Musashi and the first 11 epis of Shinsengumi.
I thought that Musashi was one of the worst Taiga productions over the past decade... would not have lasted till epi 41 if not for Sasaki Koijiro cos i'm a huge Tokio/Mabo fan. My interest died when he died. :P
Most Taiga viewers comments online on the Japanese msg boards are not positive either. Common consensus was that Ichikawa Shinnosuke lacked the presence to hold the series together. Furthermore, it did not help his cause when his ex-wife/GF scandal broke in the same year.
Ryoko-chan was very much critised for being too "wooden" by the viewers. I adore Ryoko-chan but can't help but feel that it was a mis-cast... she had great momentum going for her after Seikei Bijin, if she chosen another role in a trendy drama wisely.... she would have a better shot at the chance of being the next drama queen.
FYI, the production team of Musashi also got into trouble cos of the "similarities" between the first episode and Seven Samurai. I have not been tracking the lawsuit so don't know if they had settled it out of court with Akira Kurosawa's widow.
Shinsengumi, on the otherhand is a tad too "humourous" for me. BUT it would give it credit for daring to attempt something different from the usual Taigas. It's perhaps still early days to judge Shinsengumi... if it really flops badly... well.... least they tried to do something different.
Have anyone heard? Next year NHK Taiga Drama 2005, will star Hideaki Takizawa, Okada Junichi, Aya Ueto and Ryoko Hirosue.....haha....omoshiroi!!! Its a historical drama about Yoshitsune....who is he? A young samurai who die young? Coz i cannot imagine Takki act a 40 yrs old samurai x)
Next year's Taiga would be Yoshitune... Okada is not involved in. Okada will be involved in another period drama for NHK(i think or was it Fuji). It's not a 49 parter Taiga... rather a 4/5 parter drama special something like Kimura's Chuushingura 1/47 couple of years back.
Brief write-up on who Yoshitune is....

I'm having high hopes on this cos NHK promised to give its audience the "old-style" back with Yoshitune. The thought of seeing Aya Ueto and Ryoko Hirosue in period customes sounds lovely, don't you think... I only hope that Takki does not come across as more beautiful than the gals. Takki Ganbatte Ne!
