Coming late to this thread, as, unlike IM3, STID and MOS, I didn't see it within days of it opening (and, unlike them) I think it opened in the US before Ireland & the UK.
I really enjoyed this movie, which is the dark horse of this year's summer blockbusters. I had more fun with it than with Trek or Steel. I would not have expected a mixture of Godzilla, Transformers, Top Gun and Armageddon to have been more enjoyable than Man of Steel or Into Darkness, but it was. Really spectacular, but with wit and imagination. Plus it helped that you could actually tell what was going on in the action sequences (Mr Snyder, take note). Ron Perlman and Idris Elba brought the acting up a level too.
I gave it an A-, which is perhaps low of me, if anything. Not quite a perfect film but a lot of fun and well worth seeing. I hope it does well at the box office, it deserves to.
