This is a hilarious show, contrary to what veestar614 thinks. A laugh is a laugh is a laugh, especially since we're talking about a 1/2 hour family sitcom, not a documentary. I know zip about Latino culture (my Spanish is limited to "yo no hablo español") but this is only of my favourite shows on TV right now.
George Lopez overacts somewhat, but it is in character, and Angie Lopez (played by Constance Marie) is the perfect serious foil for George's over-the-top-ness, as are George's kids, Max and Carmen, his mother Benny and his friend Eddie.
So many comedies based on the "name brand" aspect of successful comedian end up being ego trips with the "star" so greatly overshadowing the rest of the cast that it's like they aren't even there. But on the George Lopez show, the co-stars are truly that - they get decent screen time and they get some good funny lines which they can all deliver perfectly, even the kid playing Max. And Masiela Lusha is great playing the overwrought teenage girl so much like how her father is so excitable without becoming an un-funny stereotype.
I give the show a 4.5 out of 5 stars.
