I came, I saw, I scarpered.

Or could you perhaps simply be undiscriminating, Ryan?!  The best people leave at the interval on occasion, but it's a finely-judged thing.  I'm currently achieving my 5% quota...

The Arts Theatre. It's my local. They do occasionally do plays in the original Greek/Latin, though I have never braved going to any! Your Antigone would have presumably been in Greek.

I imagine it must take someone who is either very keen on classical drama or is pretty fluent in Ancient Greek, or both, to appreciate a 3 hour play in Greek! I took GCSE Latin but I still wouldn't go & see a play in Latin.

The Play That Goes Wrong. The Treatnent. The Braille Legacy. About 5 at the Donmar. Moby Dick at the Union. King Lear at The Old Vic. We Will Rock You. The list goes on

When I left Wicked early, It was Louise Dearman as Elphie.

I'll see a play in any language. This is a thing I have learned about myself since the Globe decided to present the complete works in a whole array of languages. I mean, I would like to keep it to plays I already know so I have a basic knowledge to compensate for the fact I'm going to have to focus on the way they're saying things rather than what they're saying, but I'd be well up for a play in Ancient Greek or Latin.

I did see two musicals in Russian last year when I went to Moscow and understood exactly one word - Empress Catherine the Great shouting "Njet!" across the stage at one point. I also once saw a musical in Czech in Prague, but that was "The Count of Monte Cristo", so at least I was familiar with the story. "Jesus Christ Superstar" in Budapest was sung in Hungarian but came with English surtitles (and of course I basically knew all the lyrics by heart anyway).

I dunno, while I prefer understanding what's said on stage, I just enjoy the experience of theatre-going in different countries, see what the local audiences are like and so on. It's also quite funny trying to figure out where you need to be when you can't read the words on your ticket such as "stalls left" or "dress circle right".

I've seen lots of plays in Greek (did Classics at school) both comedy and tragedy. It helps if you know the plot already but it shouldn't be dull if the production is good. Like the foreign Shakespeares at the Globe, some of which were among the best theatrical experiences I've had (the Eastern European Henry VIs being a particular highlight along with the BSL Love's Labours Lost ) .

The Duck House - mainly cos we'd had a few cocktails before hand and fell asleep after about 15 minutes.  Oh, and a play with Keira Knightley and Damian Lewis in rhyming couplets - can't remember for the life of me what it was called - but I do remember the Spanish lady in the seat next to me who answered her phone and proceeded to have a conversation, despite me and everyone round her trying to get her to shut up!

Oh I have done the 'it's worth losing the money to save my sanity' a couple of times (usually TBH due to not being well or life making travel to London difficult) but once or twice I have simply done the 'Dear Lord I just can't be dealing with that today' and not gone though.

I did do a cheeky thing this weekend of waiting until so late in the day to book tickets that I *knew* a thing would be sold out in order to legitimately tell people "oh no I'd LOVE to have gone but look it's all sold out"

I felt less guilty when I was happily lying on my sofa drinking wine

Only ever left at the interval twice, I try to be supportive.

Once was Too Close To The Sun, which I might have stuck out on my own, out of morbid curiosity, but my guests really weren't enjoying it. We had a great thread on this on the previous forum. It was worth going just to participate in that.
The other was The 8th Fold, dreary and dull all round.
