Note that Bashir is not yawning, but doing that weird wall shuffling-screaming thing that no one understands, probably not even Siddig or the director at the time of filming.
Now MOOOOVE ALOOOOOONG HOOOOOOOOOOOOOOEM! (Whacks those weird wood sticks together.)
Yeah, don't get me wrong; Seven wasn't a bad character at all. And I completely agree that Chakotay was a bit under-defined as a character. But I simply attribute that to the writers themselves not really being interested in him enough to define him better or use him more. Maybe that was because of Beltran's acting... I love theatre and such, but I can't say I'm all that good at telling good acting from bad acting... If I can believe their feelings, that's good enough for me and I always thought Beltran shows a lot of emotion in his eyes. 😅
