Saw 10 Cloverfield Lane last night. I'm a huge fan of the first Cloverfield, and I knew going into it that it wasn't gonna be a direct sequel, but I was still super excited.
All in all, it was pretty awesome. So much of the hype is around John Goodman's performance, and rightfully so, he was fantastic. Despite it being considered a "blood relative" of Cloverfield, in no way do you HAVE to see Cloverfield in order to understand where Lane eventually ends up. There are no true direct connections mentioned in it to the first movie, so a lot of them are made within the viewers own mind...just trying to see what fits in connection to it and how it maybe changes your original thinking of just what was going on in Cloverfield. Heck, if the word 'Cloverfield' wasn't in the title, I'm not sure anyone would say "hm, this seems like it has a connection to that 2008 movie Cloverfield"
Overall, I highly recommend. I personally like the ending, not everyone will. But give it a chance if you're even considering seeing it.
