I love Harkins and this one feels like an old family member as in it actually smells musty in here -- always -- but the staff are always friendly and the popcorn is fresh. The movie theater doesn't have stadium style seating which sometimes is a plus for more relaxed days at the movies.
However, I would not recommend seeing a new release here as it is much smaller and will be much less comfortable, it's hard to find seats in the dim lighting when all the seats are on such a slight downward gradient.
I go to Shea when there is an older movie I want to see that Harkins 101 either isn't playing or has like 2 really inconvenient showings.
