Pros:

New and Unique hazards

Lots of Surprises

Loads of fun with friends

Interesting concept using gasoline to buy weapons and supplies

Not too difficult

A nice and lengthy campaign

Cons:

Some things got old pretty fast

Conclusion:

Overall the map was a load of fun and provided a new and unique experience compared to the other l4d2 maps.

Pros:

Very challenging and fun

Nicely scattered weapons and supplies

A blast to play with 4 players

Lots of vantage points to support your teamates pushing the cart

Cons:

Bots are really stupid on this map

THis map is extremely hard especially since there are no safe rooms.

Conclusion:

Overall I had a great time playing this map.  I hope that you make more tf2 tie in maps for l4d2!

Pros:

An interesting idea that could turn out to be very fun

For once legos are in a dark and depressing enviroment which I found kinda funny.

The lego town was really cool.

Cons:

Invisible walls/furniture became extremely annoying

Too dark in most places

Not enough ammo

Way too many health kits

Its never clear on where yo need to go or what you need to do

Too many witches ( I found a total of 8 when i played through the campaign)

Conclusion:

I know that this map is only the beta but it still needs a lot of work.  It really didn't feel all that legoish intill you got to the town.  If you could put more of the campaign in a town setting like that I'm sure the campaign would turn out to bea lot more fun.

Pros:

A great map that introduces many new and original ideas.

Awesome new boss fight.

Cons:

It can be a bit tricky at some times and its not  always clear on where you have to go. ( I managed to get lost a few times)

Conclusion:

This is only the preview version which was extremely short. I can't wait to see the full thing.

Pros:

I like how each corner of the fort had a different type of item.

The map is really fun to play.

The map is really open and lets you use strategys that you normally can't use in l4d2 because of how confined maps usually are.

Cons:

M60 randomly spawns in one spot

Bots will usually take weird and longer routes to find their way back to you and end up getting seperated and getting killed.

Conclusion:

Overall I really enjoyed this map. If this really is your first upload then I'm impressed.  I can't wait to see what maps you'll make in the future.(especially if they're remakes of other games like this one)
