Consumed by bitterness?
I feel a bit sorry for George. It seems like the guy is incapable of going more than a few months without laying into Shatner over one thing or another.
If you watch the TOS episodes you may be shocked by how little Sulu actually appears (asides from the very few episodes where the character was showcased).
Then watching the movies it's almost impossible not to form the impression that he lucked out and his screen time was suitably increased.
Yet, despite that and despite the fact that we're talking about a show which formed the biggest part of their acting lives over fifty years ago now, he can't help himself from taking pops at Shatner.
Pretty sad to be so all consumed by bitterness over such a long period.
On the plus side, it's pretty funny watching Shatner when he's in Takei's company. Never misses the opportunity to wind him up further.
