I'm not excited about the Sony acquisition but I'm still ride or die Alamo for the time being. I'm there at least twice a month, at either Village, South Lamar, or Lakeline, and never have any problems with loud patrons. Last time I was at a Cinemark there was a group of loud high-schoolers being obnoxious, which just reinforced my Alamo or nothing policy. The pre-shows are awesome, there are no commercials besides movie trailers, and I've never had trouble with people being loud because they enforce their no talking/texting policy.
We go to the Elf movie party every year as a family. Their special screenings are great, like the Time Capsule feature they're doing this year, and you can usually count on them to screen smaller limited-release films for at least a short time. It used to be that I had to go to the Regal Arbor Cinema to see indie stuff in the theater (after Dobie shut down). The food isn't great, but the beer selection is good and I can usually find something I like on the themed menu. And if not, bottomless popcorn.
Anyway, there's still a lot that makes the Alamo special, IMO. I'm keeping my fingers crossed that Sony doesn't fuck it all up.
