[Q]: Comfortable right out of the box. Well made. Durable. Can't vouch for the waterproofing of them, as I have learned many moons ago.....no shoes are waterproof. I refuse to test them, once you do...they never seem to be the same.
[A]: Positive


[Q]: Ugh! What a steaming pile of predictability this movie was. At least I didn't pay to see it and was able to read a software tech manual while "watching" this. The plot is thinner than the paper it was written on and the acting, well its typical Michael Bay which means you can see more believable productions at you local high school. It was easily an hour too long and the special effect have been used hundreds before. I think the saddest part was hearing Lenard Nimoy as Optimus Sentimental, I mean Sentinel. Gratuitous sci-fi pandering at it's lowest.
[A]: Negative


[Q]: I've been reading SF for just over 65 years. My SF library runs to 1800 volumes. While Empire From the Ashes may have been one of Weber's early works, it simply sparkles with imagination. If you don't enjoy it, find another genre to read. He has grown greatly in the conversations between characters (in Safehold, they are amazingly good), but they are just fine in the Dahak trio. I have recently finished reading Asamov's Foundation pentology (including the Robot inclusions) and six of Heinlein's best. Neither of them can touch Weber's attention to detail, and INTELLIGENT conversations between characters who are at the top of Safehold's heirarchy and therefore intelligent. The monologues are so good they can bring an unexpected lump in the throat. If all you want is car-chase type reading, you may skip pages, but if you want a brilliant read from a great SF writer, Weber is your guy.

Positive
