It’s a big week for “The Big Bang Theory,” which moves to Thursday nights at 8 p.m. So I’m happy to report the new season’s kickoff episode finds the show in fine form, including the protestations by Sheldon (well-Bbt deserving Emmy winner Jim Parsons) that he’s not really “dating” the other brainiac scientist he’s befriended, even if the two are discussing whether they owe it to the world to reproduce.

Meanwhile, there’s a subplot involving Howard (Simon Helberg) and a robot arm. The less given away the better, but suffice it to say that the producers do not appear inordinately confined by their new earlier 8 p.m. timeslot.

I fully expect “Big Bang” to beat up on NBC’s “Community” in its timeslot, but as I noted in my review, I have serious doubts as to whether the CBS show’s companion, “$#*! My Dad Says,” can cash in on that success. That could leave “Big Bang” a bit of an island, though probably still performing well.

Alas, the same can’t be said for CBS’ “How I Met Your Mother,” which has milked the whole “Who’s the mom?” thing for all it’s worth at this point — and brings back Rachel Bilson, however adorable she might be, to little effect.

“Mother” still has a topnotch cast, but my enthusiasm for the show has waned the last couple of seasons, and previewing the premiere did little to lure me back into it on a regular basis, especially with all the choice stuff competing for time and attention on Monday nights.

I guess that’s what CBS might call being $#*! out of luck.
