I also wouldn't call the production horrendous, but I did find it kind of weak. At least yesterday, a solid ensemble couldn't generate much excitement, given the play's generally flat, predictable dialogue and mostly cliched story. There was one moment where two characters stared each other down, practically nose-to-nose, and I genuinely wondered what would happen next -- would the play take a turn in some new direction? But it didn't. It moved on to just the sort of conclusion I (and probably many other audience members) expected.
I don't mean to suggest that such predictability is, in itself, a bad thing -- the unsurprising ending was also believable and totally justifiable. And, to be fair, it caused me to think that I should try being nicer and more understanding to people close to me. So, unlike most plays, this one actually had a positive practical effect in my life. I just didn't find it particularly good as entertainment.
