wasp,
You should watch Season1, every episode, in full.
The tatoos are not just for escape routes.
The very first use of his tatoos is to locate a bolt.
Scofield then unscrewed it from one of the benches in the prison open area,
with a coin,
he then turned that bolt into a screw driver,
to release the nut on the basin area in his cell,
to gain access to a tunnel.
The tatoos were about all the little details of how the prison was engineered.
To me, the tatoos make sense, in the show only lah.
I think your friends may have problem expressing their thoughts.
This has nothing to do with the show.
It is definitely not a lousy show.
Why drag to a Season3? Some may ask.
What else, money-making for Fox TV lah.
Season1 did very well, there's a need for Season2.
Then, even when Season2 sucks, still, there's a need for Season3.
The script writers need to makan right?
Too early to criticise Season3, the whole plot is not unfolded, yet.
Still, it is a good show.
100 times better than the HongKong: Jian1 Yu4 Fong1 Yun2...
