If you play poker, this movie will make you cringe. It's kind of like you get embarrassed just watching it. Like people said it's not in the same field as Rounders. It's not even as good as lucky you. Which I thought had a few cringey moments of dialogue. But overall still much better than this. The grand is a worthwhile movie over this aswell as a comedy with a poker story. Anyways, the acting is very subpar. The lead character just isnt super likeable. Probably stems from me just being turned off by the script. Poker movies will generally have some of the same formats and story lines to some extent. That's why execution, acting, and dialogue is so important and this movie falls short.
All in all just keep rewatching Rounders. And maybe occasionally throw in lucky you and the grand for your poker movie fix.
