i liked it, but the actual guy they had playing him looked more like a bodyguard than what i imagined Lionel Luthor to be.
I used to be indecisive. Now, I'm not so sure.

I'm a huge Smallville fan so that and mentioning that Clark and Lex used to be friends made me happy.

Was a nice touch. Lionel Luthor was one of the best characters from 'Smallville'.

I liked that they used Lionel as the Father's name, however I didn't like that Lex was shown as a Brunette. He should have been a red-head.

The Lex Sr. name in the movies was a cop-out/or way out because of fear of the possible backlash from the fans about Lex's portrayal.
That doesn't even make sense.

No Jesse played Lex Luthor JR. The film said multiple times that Lex Luthor SR was his father and in the file print that came with the ultimate collection cut BVS they had the Luthor tree and the grandfather was Lionel.

In the Comics, Lex's father was named Jules at first, then the comics changed it Lionel. The Lex Sr. name in the movies was a cop-out/or way out because of fear of the possible backlash from the fans about Lex's portrayal.

Was that just a Smallvile thing?
In the movies he is Lex Sr.
